The CentOS Linux host is missing one or more security updates.

Description

The CentOS Linux 7 host has packages installed that are affected by a vulnerability as referenced in the TuxCare CENTOS7:CLSA-2026:1793373587 advisory.

 - libdvdnav before 7.0.0 contains a heap out-of-bounds read vulnerability in dvdnav_describe_title_chapters that allows attackers to read beyond the part-of-title array by supplying an oversized vts_ttn value.
