Joe Schaefer discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain baselined WebDAV resource requests. A remote attacker could use this flaw to cause the service to crash, leading to a denial of service. (CVE-2011-1752)
Ivan Zhakov discovered that the Subversion mod_dav_svn module for Apache did not properly handle certain requests. A remote attacker could use this flaw to cause the service to consume all available resources, leading to a denial of service. (CVE-2011-1783)
Kamesh Jayachandran discovered that the Subversion mod_dav_svn module for Apache did not properly handle access control in certain situations. A remote user could use this flaw to gain access to files that would otherwise be unreadable. (CVE-2011-1921).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
