What is CVE-2015-5343?

The vulnerability in Apache Subversion is due to an integer overflow in util.c within mod_dav_svn, affecting versions 1.7.x, 1.8.x before 1.8.15, and 1.9.x before 1.9.3. This flaw allows remote authenticated users to exploit a skel-encoded request body, which can lead to a denial of service by causing a server crash or high memory consumption. Additionally, it may potentially enable the execution of arbitrary code as it triggers an out-of-bounds read and a heap-based buffer overflow.
