From openpkg@openpkg.org Thu Jul 28 13:02:49 2005 From: OpenPKG To: bugtraq@securityfocus.com Date: Thu, 28 Jul 2005 14:33:36 +0200 Subject: [OpenPKG-SA-2005.016] OpenPKG Security Advisory (fetchmail) -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ 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-2005.016 28-Jul-2005 ________________________________________________________________________ Package: fetchmail Vulnerability: denial of service OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= fetchmail-6.2.5-20050311 >= fetchmail-6.2.5-20050728 OpenPKG 2.4 <= fetchmail-6.2.5-2.4.0 >= fetchmail-6.2.5-2.4.1 OpenPKG 2.3 <= fetchmail-6.2.5-2.3.0 >= fetchmail-6.2.5-2.3.1 Dependent Packages: none Description: Ross Boylan reported a bug [0] in fetchmail [1] which turned out being a remote buffer overflow vulnerability. A malicious POP3 server could send a carefully crafted message and cause a denial of service and possibly execute arbitrary code via long UIDL responses. The Common Vulnerabilities and Exposures (CVE) project assigned the id CAN-2005-2335 [2] to the problem. Please check whether you are affected by running "/bin/openpkg rpm -q fetchmail". If you have the "fetchmail" 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 fetchmail-6.2.5-2.4.1.src.rpm ftp> bye $ /bin/openpkg rpm -v --checksig fetchmail-6.2.5-2.4.1.src.rpm $ /bin/openpkg rpm --rebuild fetchmail-6.2.5-2.4.1.src.rpm $ su - # /bin/openpkg rpm -Fvh /RPM/PKG/fetchmail-6.2.5-2.4.1.*.rpm ________________________________________________________________________ References: [0] http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=212762 [1] http://www.catb.org/~esr/fetchmail/ [2] http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-2335 [3] http://www.openpkg.org/tutorial.html#regular-source [4] http://www.openpkg.org/tutorial.html#regular-binary [5] ftp://ftp.openpkg.org/release/2.4/UPD/fetchmail-6.2.5-2.4.1.src.rpm [6] ftp://ftp.openpkg.org/release/2.3/UPD/fetchmail-6.2.5-2.3.1.src.rpm [7] ftp://ftp.openpkg.org/release/2.4/UPD/ [8] ftp://ftp.openpkg.org/release/2.3/UPD/ [9] http://www.openpkg.org/security.html#signature ________________________________________________________________________ For security reasons, this advisory was digitally signed with the OpenPGP public key "OpenPKG " (ID 63C4CB9F) of the OpenPKG project which you can retrieve from http://pgp.openpkg.org and hkp://pgp.openpkg.org.
