This signature detects attempts to exploit a known vulnerability in the Subversion Svnserve. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.
Subversion is prone to a buffer-overflow vulnerability that resides in one of its data-parsing functions. Specifically, Subversion calls an 'sscanf()' function when converting data strings to different formats. As a result, the software copies user-supplied data into an unspecified buffer without proper boundary checks. Subversion 1.0.2 and prior versions are prone to this issue.
