CVE-2011-1752

The mod_dav_svn Apache HTTPD server module can be crashed though when asked to deliver baselined WebDAV resources.

CVE-2011-1783

The mod_dav_svn Apache HTTPD server module can trigger a loop which consumes all available memory on the system.

CVE-2011-1921

The mod_dav_svn Apache HTTPD server module may leak to remote users the file contents of files configured to be unreadable by those users.

For the oldstable distribution (lenny), this problem has been fixed in version 1.5.1dfsg1-7.

For the stable distribution (squeeze), this problem has been fixed in version 1.6.12dfsg-6.

For the unstable distribution (sid), this problem has been fixed in version 1.6.17dfsg-1.

We recommend that you upgrade your subversion packages.");
