Ubuntu Security Notice USN-813-1

7th August, 2009

apr vulnerability

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

  • Ubuntu 9.04
  • Ubuntu 8.10
  • Ubuntu 8.04 LTS

Software description

  • apr

Details

Matt Lewis discovered that apr did not properly sanitize its input when
allocating memory. If an application using apr processed crafted input, a
remote attacker could cause a denial of service or potentially execute
arbitrary code as the user invoking the application.

Update instructions

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

Ubuntu 9.04:
libapr1 1.2.12-5ubuntu0.1
Ubuntu 8.10:
libapr1 1.2.12-4ubuntu0.1
Ubuntu 8.04 LTS:
libapr1 1.2.11-1ubuntu0.1

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

After a standard system upgrade you need to restart any applications using
apr, such as Subversion and Apache, to effect the necessary changes.
