USN-6855-1: libcdio vulnerability

Releases

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

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.
