### Detailed Security Report

**Security fix**: With the Alpha 3745.0.0, Beta 3732.1.0, Stable 3602.2.0, LTS 3510.3.0 releases we ship fixes for the CVEs listed below.

#### Alpha 3745.0.0

* Linux
* [CVE-2023-42755](https://nvd.nist.gov/vuln/detail/CVE-2023-42755) CVSSv3 score: n/a

* curl
* [CVE-2023-38039](https://nvd.nist.gov/vuln/detail/CVE-2023-38039) CVSSv3 score: 7.5(High)
When curl retrieves an HTTP response, it stores the incoming headers so that they can be accessed later via the libcurl headers API.
However, curl did not have a limit in how many or how large headers it would accept in a response, allowing a malicious server to stream an endless series of headers and eventually cause curl to run out of heap memory.

* glibc
* [CVE-2023-4527](https://nvd.nist.gov/vuln/detail/CVE-2023-4527) CVSSv3 score: n/a
A flaw was found in glibc. When the getaddrinfo function is called with the AF_UNSPEC address family and the system is configured with no-aaaa mode via /etc/resolv.conf, a DNS response via TCP larger than 2048 bytes can potentially disclose stack contents through the function returned address data, and may cause a crash.
* [CVE-2023-4806](https://nvd.nist.gov/vuln/detail/CVE-2023-4806) CVSSv3 score: n/a
A flaw was found in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.

* lua
* [CVE-2022-33099](https://nvd.nist.gov/vuln/detail/CVE-2022-33099) CVSSv3 score: 7.5(High)
An issue in the component luaG_runerror of Lua v5.4.4 and below leads to a heap-buffer overflow when a recursive error occurs.

* mit-krb5
* [CVE-2023-36054](https://nvd.nist.gov/vuln/detail/CVE-2023-36054) CVSSv3 score: 6.5(Medium)
lib/kadm5/kadm_rpc_xdr.c in MIT Kerberos 5 (aka krb5) before 1.20.2 and 1.21.x before 1.21.1 frees an uninitialized pointer. A remote authenticated user can trigger a kadmind crash. This occurs because _xdr_kadm5_principal_ent_rec does not validate the relationship between n_key_data and the key_data array count.

* procps
* [CVE-2023-4016](https://nvd.nist.gov/vuln/detail/CVE-2023-4016) CVSSv3 score: 5.5(Medium)
Under some circumstances, this weakness allows a user who has access to run the “ps” utility on a machine, the ability to write almost unlimited amounts of unfiltered data into the process heap.

* samba
* [CVE-2021-44142](https://nvd.nist.gov/vuln/detail/CVE-2021-44142) CVSSv3 score: 8.8(High)
The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.
* [CVE-2022-1615](https://nvd.nist.gov/vuln/detail/CVE-2022-1615) CVSSv3 score: 5.5(Medium)
In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values.

#### Beta 3732.1.0

* Go
* [CVE-2023-29402](https://nvd.nist.gov/vuln/detail/CVE-2023-29402) CVSSv3 score: 9.8(Critical)
The go command may generate unexpected code at build time when using cgo. This may result in unexpected behavior when running a go program which uses cgo. This may occur when running an untrusted module which contains directories with newline characters in their names. Modules which are retrieved using the go command, i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e. GO111MODULE=off, may be affected).
* [CVE-2023-29403](https://nvd.nist.gov/vuln/detail/CVE-2023-29403) CVSSv3 score: 7.8(High)
On Unix platforms, the Go runtime does not behave differently when a binary is run with the setuid/setgid bits. This can be dangerous in certain cases, such as when dumping memory state, or assuming the status of standard i/o file descriptors. If a setuid/setgid binary is executed with standard I/O file descriptors closed, opening any files can result in unexpected content being read or written with elevated privileges. Similarly, if a setuid/setgid program is terminated, either via panic or signal, it may leak the contents of its registers.
* [CVE-2023-29404](https://nvd.nist.gov/vuln/detail/CVE-2023-29404) CVSSv3 score: 9.8(Critical)
The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "#cgo LDFLAGS" directive. The arguments for a number of flags which are non-optional are incorrectly considered optional, allowing disallowed flags to be smuggled through the LDFLAGS sanitization. This affects usage of both the gc and gccgo compilers.
* [CVE-2023-29405](https://nvd.nist.gov/vuln/detail/CVE-2023-29405) CVSSv3 score: 9.8(Critical)
The go command may execute arbitrary code at build time when using cgo. This may occur when running "go get" on a malicious module, or when running any other command which builds untrusted code. This is can by triggered by linker flags, specified via a "#cgo LDFLAGS" directive. Flags containing embedded spaces are mishandled, allowing disallowed flags to be smuggled through the LDFLAGS sanitization by including them in the argument of another flag. This only affects usage of the gccgo compiler.
* [CVE-2023-29406](https://nvd.nist.gov/vuln/detail/CVE-2023-29406) CVSSv3 score: 6.5(Medium)
The HTTP/1 client does not fully validate the contents of the Host header. A maliciously crafted Host header can inject additional headers or entire requests. With fix, the HTTP/1 client now refuses to send requests containing an invalid Request.Host or Request.URL.Host value.
* [CVE-2023-29409](https://nvd.nist.gov/vuln/detail/CVE-2023-29409) CVSSv3 score: 5.3(Medium)
Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. With fix, the size of RSA keys transmitted during handshakes is restricted to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable.
* [CVE-2023-39318](https://nvd.nist.gov/vuln/detail/CVE-2023-39318) CVSSv3 score: 6.1(Medium)
The html/template package does not properly handle HTML-like "" comment tokens, nor hashbang "#!" comment tokens, in <script> contexts. This may cause the template parser to improperly interpret the contents of <script> contexts, causing actions to be improperly escaped. This may be leveraged to perform an XSS attack.
* [CVE-2023-39319](https://nvd.nist.gov/vuln/detail/CVE-2023-39319) CVSSv3 score: 6.1(Medium)
The html/template package does not apply the proper rules for handling occurrences of "<script", "<!--", and "</script" within JS literals in <script> contexts. This may cause the template parser to improperly consider script contexts to be terminated early, causing actions to be improperly escaped. This could be leveraged to perform an XSS attack.
* [CVE-2023-39320](https://nvd.nist.gov/vuln/detail/CVE-2023-39320) CVSSv3 score: 9.8(Critical)
The go.mod toolchain directive, introduced in Go 1.21, can be leveraged to execute scripts and binaries relative to the root of the module when the "go" command was executed within the module. This applies to modules downloaded using the "go" command from the module proxy, as well as modules downloaded directly using VCS software.
* [CVE-2023-39321](https://nvd.nist.gov/vuln/detail/CVE-2023-39321) CVSSv3 score: 7.5(High)
Processing an incomplete post-handshake message for a QUIC connection can cause a panic.
* [CVE-2023-39322](https://nvd.nist.gov/vuln/detail/CVE-2023-39322) CVSSv3 score: 7.5(High)
QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now consistently reject messages larger than 65KiB in size.

* Linux
* [CVE-2020-36516](https://nvd.nist.gov/vuln/detail/CVE-2020-36516) CVSSv3 score: 5.9(Medium)
An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session or terminate that session.
* [CVE-2021-26401](https://nvd.nist.gov/vuln/detail/CVE-2021-26401) CVSSv3 score: 5.6(Medium)
LFENCE/JMP (mitigation V2-2) may not sufficiently mitigate CVE-2017-5715 on some AMD CPUs.
* [CVE-2021-33135](https://nvd.nist.gov/vuln/detail/CVE-2021-33135) CVSSv3 score: 5.5(Medium)
Uncontrolled resource consumption in the Linux kernel drivers for Intel(R) SGX may allow an authenticated user to potentially enable denial of service via local access.
* [CVE-2021-33655](https://nvd.nist.gov/vuln/detail/CVE-2021-33655) CVSSv3 score: 6.7(Medium)
When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of bounds.
* [CVE-2021-3923](https://nvd.nist.gov/vuln/detail/CVE-2021-3923) CVSSv3 score: 2.3(Low)
A flaw was found in the Linux kernel's implementation of RDMA over infiniband. An attacker with a privileged local account can leak kernel stack information when issuing commands to the /dev/infiniband/rdma_cm device node. While this access is unlikely to leak sensitive user information, it can be further used to defeat existing kernel protection mechanisms.

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a kernel oops condition that results in a denial of service.
* [CVE-2022-2196](https://nvd.nist.gov/vuln/detail/CVE-2022-2196) CVSSv3 score: 8.8(High)
A regression exists in the Linux Kernel within KVM: nVMX that allowed for speculative execution attacks. L2 can carry out Spectre v2 attacks on L1 due to L1 thinking it doesn't need retpolines or IBPB after running L2 due to KVM (L0) advertising eIBRS support to L1. An attacker at L2 with code execution can execute code on an indirect branch on the host machine. We recommend upgrading to Kernel 6.2 or past commit 2e7eab81425a

Linux PV device frontends vulnerable to attacks by backends T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Several Linux PV device frontends are using the grant table interfaces for removing access rights of the backends in ways being subject to race conditions, resulting in potential data leaks, data corruption by malicious backends, and denial of service triggered by malicious backends: blkfront, netfront, scsifront and the gntalloc driver are testing whether a grant reference is still in use. If this is not the case, they assume that a following removal of the granted access will always succeed, which is not true in case the backend has mapped the granted page between those two operations. As a result the backend can keep access to the memory page of the guest no matter how the page will be used after the frontend I/O has finished.

Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module/firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out the target with an equivalent dm-linear target and bypass verification till reboot. This allows root to bypass LoadPin and can be used to load untrusted and unverified kernel modules and firmware, which implies arbitrary kernel execution and persistence for peripherals that do not verify firmware updates.
