Synopsis

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

Description

The version of tigervnc installed on the remote host is prior to 1.16.2. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2026-108-01 advisory.

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

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