20 February 2008

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

Details

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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 7.10
libcdio6 - 0.76-1ubuntu2.7.10.1
Ubuntu 7.04
libcdio6 - 0.76-1ubuntu2.7.04.1
Ubuntu 6.10
libcdio6 - 0.76-1ubuntu1.6.10.1
Ubuntu 6.06 LTS
libcdio6 - 0.76-1ubuntu1.6.06.1

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

In general, a standard system upgrade is sufficient to effect the necessary changes.
