-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ________________________________________________________________________ OpenPKG Security Advisory The OpenPKG Project OpenPKG-SA-2005.005 05-Apr-2005 ________________________________________________________________________ Package: imapd Vulnerability: arbitrary code execution OpenPKG Specific: no Affected Releases: Affected Packages: Corrected Packages: OpenPKG CURRENT <= imapd-2.2.10-20050129 >= imapd-2.2.11-20050214 OpenPKG 2.2 <= imapd-2.2.8-2.2.1 >= imapd-2.2.8-2.2.2 Dependent Packages: none Description: Sean Larsson discovered several vulnerabilities in the Cyrus IMAP Server [0] that could allow a remote attacker to execute machine code in the context of the server process. The Cyrus Electronic Messaging Project identified the affected server logic and released a security advisory [1]. Essentially, the application is affected by multiple one byte buffer overflows affecting the IMAP annotate extension and cached header handling routines. Additionally, stack based overflows affecting the fetchnews, backend, and imapd logic exist as well. The Common Vulnerabilities and Exposures (CVE) project assigned the identifier CAN-2005-0546 [2] to the problem. Please check whether you are affected by running "<prefix>/bin/openpkg rpm -q imapd". If you have the "imapd" 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 previous release OpenPKG 2.2, perform the following operations to permanently fix the security problem. $ ftp ftp> bin ftp> cd release/2.2/UPD ftp> get imapd-2.2.8-2.2.2.src.rpm ftp> bye $ <prefix>/bin/openpkg rpm -v --checksig imapd-2.2.8-2.2.2.src.rpm $ <prefix>/bin/openpkg rpm --rebuild imapd-2.2.8-2.2.2.src.rpm $ su - # <prefix>/bin/openpkg rpm -Fvh <prefix>/RPM/PKG/imapd-2.2.8-2.2.2.*.rpm ________________________________________________________________________ References: [0] [1] [2] [3] [4] [5] [6] [7] ________________________________________________________________________ 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 and hkp:// Follow the instructions on for details on how to verify the integrity of this advisory. ________________________________________________________________________ -----BEGIN PGP SIGNATURE----- Comment: OpenPKG <> iD8DBQFCUqPxgHWT4GPEy58RAt+GAKDOatq1M0OtZNO4Jdq0prnrNrbDowCgzbfn 74UcLwGpm7wfbOoSpT7Nu4M= =z4o5 -----END PGP SIGNATURE----- ______________________________________________________________________ The OpenPKG Project Project Announcement List
