-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-security@xxxxxxxxxxx openpkg@xxxxxxxxxxx OpenPKG-SA-2005.007 10-Jun-2005 ________________________________________________________________________ Package: cvs Vulnerability: denial of service OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= cvs-1.12.11-20050408 >= cvs-1.12.11-20050504 OpenPKG 2.3 <= cvs-1.12.9-2.3.0 >= cvs-1.12.9-2.3.1 OpenPKG 2.2 <= cvs-1.12.9-2.2.0 >= cvs-1.12.9-2.2.1 Dependent Packages: none Description: According to a Debian bug report [0], a Denial of Service (DoS) vulnerability exists in the embedded ZLib [1] compression logic of the Concurrent Versions Systems (CVS). The problem involves incorrect error handling in the inflate() and inflateBack() functions. The Common Vulnerabilities and Exposures (CVE) project assigned the identifier CAN-2004-0797 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q cvs". If you have the "cvs" 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][6], fetch it from the OpenPKG FTP service [7][8] or a mirror location, verify its integrity [9], 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 2.3, perform the following operations to permanently fix the security problem (for other releases adjust accordingly). $ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.3/UPD ftp> get cvs-1.12.9-2.3.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig cvs-1.12.9-2.3.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild cvs-1.12.9-2.3.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/cvs-1.12.9-2.3.1.*.rpm ________________________________________________________________________ References: [0] http://bugs.debian.org/252253 [1] http://www.gzip.org/zlib/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-0797 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.3/UPD/cvs-1.12.9-2.3.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.2/UPD/cvs-1.12.9-2.2.1.src.rpm [7] ftp://ftp.openpkg.org/release/2.3/UPD/ [8] ftp://ftp.openpkg.org/release/2.2/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG <openpkg@xxxxxxxxxxx>" (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
