USN-812-1: Subversion vulnerability

Ubuntu Security Notice USN-812-1

7th August, 2009

subversion vulnerability

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

  • Ubuntu 9.04
  • Ubuntu 8.10
  • Ubuntu 8.04 LTS
  • Ubuntu 6.06 LTS

Software description

  • subversion

Details

Matt Lewis discovered that Subversion did not properly sanitize its input
when processing svndiff streams, leading to various integer and heap
overflows. If a user or automated system processed crafted input, a remote
attacker could cause a denial of service or potentially execute arbitrary
code as the user processing the input.

Update instructions

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

Ubuntu 9.04:
libsvn1 1.5.4dfsg1-1ubuntu2.1
Ubuntu 8.10:
libsvn1 1.5.1dfsg1-1ubuntu2.1
Ubuntu 8.04 LTS:
libsvn1 1.4.6dfsg1-2ubuntu1.1
Ubuntu 6.06 LTS:
libsvn0 1.3.1-3ubuntu1.2

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 that
use Subversion, such as Apache when using mod_dav_svn, to effect the
necessary changes.
