subversion vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

  • Ubuntu 14.04 LTS
  • Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Subversion.

Software Description:

  • 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 man 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)

Update instructions:

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

Ubuntu 14.04 LTS:
libsvn1 1.8.8-1ubuntu3.1
subversion 1.8.8-1ubuntu3.1

Ubuntu 12.04 LTS:
libapache2-svn 1.6.17dfsg-3ubuntu3.4
libsvn1 1.6.17dfsg-3ubuntu3.4
subversion 1.6.17dfsg-3ubuntu3.4

In general, a standard system update will make all the necessary changes.
