Synopsis

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

Description

The CentOS Linux 8.4 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.4:CLSA-2026:1780660837 advisory.

 - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, domain=path authorization is checked before final file open/use. A symlink swap between check-time and use-time bypasses policy-denied read/write. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. (CVE-2026-28689)

 - ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-16 and 6.9.13-41, MAT decoder uses 32-bit arithmetic due to incorrect parenthesization resulting in a heap over-read. This vulnerability is fixed in 7.1.2-16 and 6.9.13-41. (CVE-2026-28692)
