Multiple integer overflows, leading to heap-based buffer overflows in the
Subversion client and server might allow remote attackers to execute
Subversion is a versioning system designed to be a replacement for CVS.
Matt Lewis of Google reported multiple integer overflows in the
libsvn_delta library, possibly leading to heap-based buffer overflows.
A remote attacker with commit access could exploit this vulnerability
by sending a specially crafted commit to a Subversion server, or a
remote attacker could entice a user to check out or update a repository
from a malicious Subversion server, possibly resulting in the execution
of arbitrary code with the privileges of the user running the server or
There is no known workaround at this time.
All Subversion users should upgrade to the latest version:
