libcdio vulnerability

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 24.04 LTS
• Ubuntu 23.10
• Ubuntu 22.04 LTS
• Ubuntu 20.04 LTS
• Ubuntu 18.04 LTS
• Ubuntu 16.04 LTS
• Ubuntu 14.04 LTS

Summary:

libcdio could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:

• libcdio: C++ library to read and control CD-ROM (development files)

Details:

Mansour Gashasbi discovered that libcdio incorrectly handled certain
memory operations when parsing an ISO file, leading to a buffer overflow
vulnerability. An attacker could use this to cause a denial of service
or possibly execute arbitrary code.
