Apache Subversion 1.7.x < 1.7.20 / 1.8.x < 1.8.12 Multiple Vulnerabilities
high Nessus Network Monitor Plugin ID 8972
Synopsis
The remote host is running a version of Apache Subversion (SVN) that contains multiple vulnerabilities.Description
The version of Apache Subversion installed on the remote host is 1.7.x prior to 1.7.20, or 1.8.x prior to 1.8.12 and is affected by the following vulnerabilities :- 'mod_dav_svn' and 'svnserve' are vulnerable to a remotely triggerable assertion DoS vulnerability for certain requests with dynamically evaluated revision numbers. Assertion will cause svnserve process or the process hosting m'od_dav_svn' module (Apache) to abort. (CVE-2015-0248)
- The 'mod_dav_svn' module allows setting arbitrary 'svn:author' property values when committing new revisions. This can be accomplished using a specially crafted sequence of requests. A malicious committer can fake 'svn:author' values on his commits. (CVE-2015-0251)
- A denial of service vulnerability affects Subversion HTTP servers with FSFS repositories. The 'mod_dav_svn' module may use excessive amounts of memory when processing REPORT requests that require traversing through a large number of FSFS repository nodes (files and directories). With a specially crafted report query, a malicious actor could cause a denial of service condition. Note: This issue only affects 1.8.x installations. (CVE-2015-0202)
