Synopsis

The remote Slackware Linux host is missing a security update to libXfont2.

Description

The version of libXfont2 installed on the remote host is prior to 2.0.9. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2026-218-01 advisory.

 New libXfont2 packages are available for Slackware 15.0 and -current to fix security issues.
