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

http://security.gentoo.org/

Severity:	high
Title:	Subversion: Remote execution of arbitrary code
Date:	08/18/2009
Bugs:	#280494
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	Architecture(s)
dev-util/subversion	< 1.6.4	>= 1.6.4	All supported architectures

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"
