Synopsis

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

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2022:0892 advisory.

The libarchive programming library can create and read several different streaming archive formats, including GNU tar, cpio, and ISO 9660 CD-ROM images. Libarchive is used notably in the bsdtar utility, scripting language bindings such as python-libarchive, and several popular desktop file managers.

Security Fix(es):

* libarchive: extracting a symlink with ACLs modifies ACLs of target (CVE-2021-23177)

* libarchive: symbolic links incorrectly followed when changing modes, times, ACL and flags of a file while extracting an archive (CVE-2021-31566)
