ALAS-2015-587


Amazon Linux AMI Security Advisory: ALAS-2015-587
Advisory Release Date: 2015-08-24 22:35 Pacific
Severity: Medium

Issue Overview:

The mod_dav_svn server in Subversion 1.8.0 through 1.8.11 allows remote attackers to cause a denial of service (memory consumption) via a large number of REPORT requests, which trigger the traversal of FSFS repository nodes. (CVE-2015-0202 )

An assertion failure flaw was found in the way the SVN server processed certain requests with dynamically evaluated revision numbers. A remote attacker could use this flaw to cause the SVN server (both svnserve and httpd with the mod_dav_svn module) to crash. (CVE-2015-0248 )

It was found that the mod_dav_svn module did not properly validate the svn:author property of certain requests. An attacker able to create new revisions could use this flaw to spoof the svn:author property. (CVE-2015-0251 )
