USN-1096-1: Subversion vulnerability

Releases

• Ubuntu 10.10
• Ubuntu 10.04
• Ubuntu 9.10
• Ubuntu 8.04
• Ubuntu 6.06

Packages

• subversion - Advanced version control system

Details

Philip Martin discovered that the Subversion mod_dav_svn module for Apache
did not properly handle certain requests containing a lock token. A remote
attacker could use this flaw to cause the service to crash, leading to a
denial of service.

Update instructions

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

Ubuntu 9.10

• libapache2-svn - 1.6.5dfsg-1ubuntu1.2

Ubuntu 8.04

• libapache2-svn - 1.4.6dfsg1-2ubuntu1.3

Ubuntu 6.06

• libapache2-svn - 1.3.1-3ubuntu1.4

Ubuntu 10.10

• libapache2-svn - 1.6.12dfsg-1ubuntu1.2

Ubuntu 10.04

• libapache2-svn - 1.6.6dfsg-2ubuntu1.2

After a standard system update you need to restart any applications that
use Subversion, such as Apache when using mod_dav_svn, to make all the
necessary changes.
