Synopsis

The remote Red Hat host is missing one or more security updates.

Description

The remote Redhat Enterprise Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2023:1677 advisory.

- git: gitattributes parsing integer overflow (CVE-2022-23521)

- git: Heap overflow in `git archive`, `git log --format` leading to RCE (CVE-2022-41903)

- ALSA: pcm: Move rwsem lock inside snd_ctl_elem_read to prevent UAF (CVE-2023-0266)

- A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel's OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system. (CVE-2023-0386)

- nss: Arbitrary memory write via PKCS 12 (CVE-2023-0767)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected redhat-virtualization-host-image-update package.
