Subversion: Remote execution of arbitrary code — GLSA 200908-05

Multiple integer overflows, leading to heap-based buffer overflows in the Subversion client and server might allow remote attackers to execute arbitrary code.

Affected Packages

dev-util/subversion on all architectures
Affected versions < 1.6.4
Unaffected versions >= 1.6.4

Background

Subversion is a versioning system designed to be a replacement for CVS.

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"
