Description

A remote overflow exists in Subversion. The Subversion fails to check the boundary when calling sscanf() to decode old-styled date strings. By sending a specially crafted request via a DAV2 REPORT query or get-dated-rev svn-protocol command, a remote attacker can cause a buffer overflow and execute arbitrary code, resulting in a loss of integrity.
