CentOS 9 : xz-5.2.5-8.el9

high Nessus Plugin ID 191212

Language:

Synopsis

The remote CentOS host is missing a security update for xz.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the xz-5.2.5-8.el9 build changelog.

 - An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system. (CVE-2022-1271)

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

Solution

Update the CentOS 9 Stream xz package.
