USN-812-1: Subversion vulnerability

8 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


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 versions:

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:

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.
