OpenPKG Security Advisory The OpenPKG Project http://www.openpkg.org/security.html http://www.openpkg.org openpkg-security@openpkg.org openpkg@openpkg.org OpenPKG-SA-2005.021 10-Sep-2005

Package: squid Vulnerability: denial of service OpenPKG Specific: no

Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= squid-2.5.10-20050709 >= squid-2.5.10-20050910 OpenPKG 2.4 <= squid-2.5.10-2.4.0 >= squid-2.5.10-2.4.1
OpenPKG 2.3 <= squid-2.5.9-2.3.0 >= squid-2.5.9-2.3.1

Dependent Packages: none

Description: Two Denial of Service (DoS) security issues were discovered in the Squid [0] Internet proxy. The first DoS is possible via certain aborted requests that trigger an assertion error related to "STORE_PENDING". The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2005-2794 [1] to the problem. The second problem allows remote attackers to cause a DoS via certain crafted requests and SSL timeouts. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2005-2796 [2] to the problem.

Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q squid". If you have the "squid" 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 2.4, perform the following operations to permanently fix the security problem (for other releases adjust accordingly).

$ ftp ftp.openpkg.org ftp> bin ftp> cd release/2.4/UPD ftp> get squid-2.5.10-2.4.1.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig squid-2.5.10-2.4.1.src.rpm $ <prefix>/bin/openpkg rpm --rebuild squid-2.5.10-2.4.1.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/squid-2.5.10-2.4.1.*.rpm
