libcdio vulnerability

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

  • Ubuntu 7.10
  • Ubuntu 7.04
  • Ubuntu 6.10
  • Ubuntu 6.06 LTS

Software description

  • libcdio


Devon Miller discovered that the iso-info and cd-info tools did not
properly perform bounds checking. If a user were tricked into using
these tools with a crafted iso image, an attacker could cause a
denial of service (core dump) and possibly execute arbitrary code.

Ubuntu 7.10:
libcdio6 0.76-1ubuntu2.7.10.1
