Slackware Linux 14.0 / 14.1 / 14.2 / 15.0 / current xz Vulnerability (SSA:2022-104-03)

high Nessus Plugin ID 159747

Language:

Synopsis

The remote Slackware Linux host is missing a security update to xz.

Description

The version of xz installed on the remote host is prior to 5.2.5. It is, therefore, affected by a vulnerability as referenced in the SSA:2022-104-03 advisory.

 - 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

Upgrade the affected xz package.
