USN-2316-1: Subversion vulnerabilities

Releases

• Ubuntu 14.04 ESM
• Ubuntu 12.04

Packages

• subversion - Advanced version control system

Details

Lieven Govaerts discovered that the Subversion mod_dav_svn module
incorrectly handled certain request methods when SVNListParentPath was
enabled. A remote attacker could use this issue to cause the server to
crash, resulting in a denial of service. This issue only affected Ubuntu
12.04 LTS. (CVE-2014-0032)

Ben Reser discovered that Subversion did not correctly validate SSL
certificates containing wildcards. A remote attacker could exploit this to
perform a machine-in-the-middle attack to view sensitive information or alter
encrypted communications. (CVE-2014-3522)

Bert Huijben discovered that Subversion did not properly handle cached
credentials. A malicious server could possibly use this issue to obtain
credentials cached for a different server. (CVE-2014-3528)
