Subversion: Remote execution of arbitrary code


1.  Gentoo Linux Security Advisory

Version Information

Advisory Reference GLSA 200908-05 / subversion
Release Date August 18, 2009
Latest Revision August 18, 2009: 01
Impact high
Exploitable remote
Package Vulnerable versions Unaffected versions Architecture(s)
dev-util/subversion < 1.6.4 >= 1.6.4 All supported architectures

Related bugreports: #280494


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

2.  Impact Information


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 client.

3.  Resolution Information


There is no known workaround at this time.


All Subversion users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-util/subversion-1.6.4"
