Description Moritz Muehlenhoff univentionstaff 2014-11-26 12:49:33 CET 
The --pid-file option of svnserve does not validate whether the PID file is a symlink, allowing denial of service (CVE-2013-4277)

Denial of service in mod_dav_svn (CVE-2014-0032)
Comment 1 Moritz Muehlenhoff univentionstaff 2014-12-22 15:56:33 CET 
Denial of service in mod_dav_svn (CVE-2014-3580)
Comment 2 Moritz Muehlenhoff univentionstaff 2015-02-04 09:01:53 CET 
> Denial of service in mod_dav_svn (CVE-2014-0032)
> Denial of service in mod_dav_svn (CVE-2014-3580)

This was fixed during the import of the Wheezy 7.8 point update in Bug 37511

CVE-2013-4277 is a non-standard option and even if it were configured to /tmp, the kernel-level mitigations present in all supported UCS kernels render this non-exploitable, so we won't address this with a code change.
