ID: 200908-05
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Synopsis
========
Multiple integer overflows, leading to heap-based buffer overflows in
the Subversion client and server might allow remote attackers to
execute arbitrary code.
Background
==========
Subversion is a versioning system designed to be a replacement for CVS.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-util/subversion < 1.6.4 >= 1.6.4
Description
===========
Matt Lewis of Google reported multiple integer overflows in the
libsvn_delta library, possibly leading to heap-based buffer overflows.
Impact
======
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
client.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Subversion users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose =dev-util/subversion-1.6.4
