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.
