Gentoo Linux Security Advisory

Title: Subversion: Remote execution of arbitrary code (GLSA 200908-05)
Severity: high
Exploitable: remote
Date: August 18, 2009
Bug(s): #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: dev-util/subversion
Vulnerable: < 1.6.4
Unaffected: >= 1.6.4
Architectures: 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:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-util/subversion-1.6.4"


References

CVE-2009-2411
