USN-812-1: Subversion vulnerability

Publication date

Overview

Subversion vulnerability

Releases

Packages

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

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.
