14 DAY TRIAL // In a security notice, Canonical has published details about Subversion vulnerabilities for its Ubuntu 13.04, Ubuntu 12.10, and Ubuntu 12.04 LTS operating systems.
According to Canonical, several security issues have been fixed in Subversion.
For example, it has been discovered that the Subversion mod_dav_svn module for Apache did not properly handle a large number of properties.
A remote authenticated attacker could have used this flaw to cause a memory consumption, which could lead to a denial of service.
For a more detailed description of the security problems, you can visit Canonical's security notification.
The security flaws can be fixed if you upgrade your system(s) to the latest Subversion package, specific to each distribution. To apply the update, run the Update Manager application.
In general, a standard system update will make all the necessary changes. A system restart will not be needed to implement the changes.
