Synopsis

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

Description

The version of expat installed on the remote host is prior to 2.7.4. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2026-031-01 advisory.

 New expat packages are available for Slackware 15.0 and -current to fix security issues.

Tenable has extracted the preceding description block directly from the expat security advisory.
