HTTP: Apache Subversion mod_dav_svn Integer Overflow
This signature detects attempts to exploit Heap overflow vulnerability in the mod_dav_svn of Apache Subversion web servers. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.
Extended Description
Integer overflow in util.c in mod_dav_svn in Apache Subversion 1.7.x, 1.8.x before 1.8.15, and 1.9.x before 1.9.3 allows remote authenticated users to cause a denial of service (subversion server crash or memory consumption) and possibly execute arbitrary code via a skel-encoded request body, which triggers an out-of-bounds read and heap-based buffer overflow.
