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.

Updated subversion packages fix security vulnerabilities
Updated subversion packages fix security vulnerability:
Subversion's httpd servers are vulnerable to a remotely triggerable heap-based buffer overflow and out-of-bounds read caused by an integer overflow when parsing skel-encoded request bodies (CVE-2015-5343).
This allows remote attackers with write access to a repository to cause a denial of service or possibly execute arbitrary code under the context of the httpd process. 32-bit server versions are vulnerable to both the denial-of-service attack and possible arbitrary code execution. 64-bit server versions are only vulnerable to the denial-of-service attack.
