OpenPKG-SA-2004.023 19-May-2004
________________________________________________________________________

Package: subversion
Vulnerability: remote code execution
OpenPKG Specific: no

Affected Releases: Affected Packages: Corrected Packages:
OpenPKG CURRENT <= subversion-1.0.2-20040518 >= subversion-1.0.3-20040519
OpenPKG 2.0 <= subversion-1.0.0-2.0.1 >= subversion-1.0.0-2.0.2
OpenPKG 1.3 N.A. N.A.

Dependent Packages: none

Description:
Stefan Esser discovered [1] a remote vulnerability in the Subversion
[0] version control system. Subversion versions up to 1.0.2 are
vulnerable to a date parsing vulnerability which can be abused to
allow remote code execution on Subversion servers and therefore
could lead to a repository compromise. The Common Vulnerabilities
and Exposures (CVE) project assigned the id CAN-2004-0397 [2] to the
problem.

Please check whether you are affected by running "<prefix>/bin/rpm -q
subversion". If you have the "subversion" package installed and its
version is affected (see above), we recommend that you immediately
upgrade it (see Solution). [3][4]

Solution:
Select the updated source RPM appropriate for your OpenPKG release
[5], fetch it from the OpenPKG FTP service [6] or a mirror location,
verify its integrity [7], build a corresponding binary RPM from it
[3] and update your OpenPKG installation by applying the binary RPM
[4]. For the most recent release OpenPKG 2.0, perform the following
operations to permanently fix the security problem (for other releases
adjust accordingly).

$ ftp ftp.openpkg.org
ftp> bin
ftp> cd release/2.0/UPD
ftp> get subversion-1.0.0-2.0.2.src.rpm
ftp> bye
$ <prefix>/bin/openpkg rpm -v --checksig subversion-1.0.0-2.0.2.src.rpm
$ <prefix>/bin/openpkg rpm --rebuild subversion-1.0.0-2.0.2.src.rpm
$ su -
# <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/subversion-1.0.0-2.0.2.*.rpm
