The version of AHV installed on the remote host is prior to AHV-10.0.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AHV-10.0.1 advisory.

  - An issue was discovered in libexpat before 2.6.3. nextScaffoldPart in xmlparse.c can have an integer     overflow for m_groupSize on 32-bit platforms (where UINT_MAX equals SIZE_MAX). (CVE-2024-45492)

  - Flatpak is a Linux application sandboxing and distribution framework. Prior to versions 1.14.0 and     1.15.10, a malicious or compromised Flatpak app using persistent directories could access and write files     outside of what it would otherwise have access to, which is an attack on integrity and confidentiality.
    When `persistent=subdir` is used in the application permissions (represented as `--persist=subdir` in the     command-line interface), that means that an application which otherwise doesn't have access to the real     user home directory will see an empty home directory with a writeable subdirectory `subdir`. Behind the     scenes, this directory is actually a bind mount and the data is stored in the per-application directory as     `~/.var/app/$APPID/subdir`. This allows existing apps that are not aware of the per-application directory     to still work as intended without general home directory access. However, the application does have write     access to the application directory `~/.var/app/$APPID` where this directory is stored. If the source     directory for the `persistent`/`--persist` option is replaced by a symlink, then the next time the     application is started, the bind mount will follow the symlink and mount whatever it points to into the     sandbox. Partial protection against this vulnerability can be provided by patching Flatpak using the     patches in commits ceec2ffc and 98f79773. However, this leaves a race condition that could be exploited by     two instances of a malicious app running in parallel. Closing the race condition requires updating or     patching the version of bubblewrap that is used by Flatpak to add the new `--bind-fd` option using the     patch and then patching Flatpak to use it. If Flatpak has been configured at build-time with     `-Dsystem_bubblewrap=bwrap` (1.15.x) or `--with-system-bubblewrap=bwrap` (1.14.x or older), or a similar     option, then the version of bubblewrap that needs to be patched is a system copy that is distributed     separately, typically `/usr/bin/bwrap`. This configuration is the one that is typically used in Linux     distributions. If Flatpak has been configured at build-time with `-Dsystem_bubblewrap=` (1.15.x) or with     `--without-system-bubblewrap` (1.14.x or older), then it is the bundled version of bubblewrap that is     included with Flatpak that must be patched. This is typically installed as `/usr/libexec/flatpak-bwrap`.
    This configuration is the default when building from source code. For the 1.14.x stable branch, these     changes are included in Flatpak 1.14.10. The bundled version of bubblewrap included in this release has     been updated to 0.6.3. For the 1.15.x development branch, these changes are included in Flatpak 1.15.10.
    The bundled version of bubblewrap in this release is a Meson wrap subproject, which has been updated to     0.10.0. The 1.12.x and 1.10.x branches will not be updated for this vulnerability. Long-term support OS     distributions should backport the individual changes into their versions of Flatpak and bubblewrap, or     update to newer versions if their stability policy allows it. As a workaround, avoid using applications     using the `persistent` (`--persist`) permission. (CVE-2024-42472)

  - A vulnerability was found in GNU Nano that allows a possible privilege escalation through an insecure     temporary file. If Nano is killed while editing, a file it saves to an emergency file with the permissions     of the running user provides a window of opportunity for attackers to escalate privileges through a     malicious symlink. (CVE-2024-5742)

  - The ipaddress module contained incorrect information about whether certain IPv4 and IPv6 addresses were     designated as globally reachable or private. This affected the is_private and is_global properties of     the ipaddress.IPv4Address, ipaddress.IPv4Network, ipaddress.IPv6Address, and ipaddress.IPv6Network     classes, where values wouldn't be returned in accordance with the latest information from the IANA     Special-Purpose Address Registries. CPython 3.12.4 and 3.13.0a6 contain updated information from these     registries and thus have the intended behavior. (CVE-2024-4032)

  - There is a MEDIUM severity vulnerability affecting CPython. Regular expressions that allowed excessive     backtracking during tarfile.TarFile header parsing are vulnerable to ReDoS via specifically-crafted tar     archives. (CVE-2024-6232)
