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.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
