security advisoryupdatebuffer overflowFedora Core 3 Exim Update FEDORA-2005-001 Moderate Buffer Overflow
This erratum fixes two relatively minor security issues which were discovered in Exim in the last few weeks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-0021 and CAN-2005-0022 to these, respectively.. ---------------------------------------------------------------------Fedora Update Notification FEDORA-2005-001 2005-01-06 ---------------------------------------------------------------------Product : Fedora Core 3 Name : exim Version : 4.43 Release : 1.FC3.1 Summary : The exim mail transfer agent Description : Exim is a mail transport agent (MTA) developed at the University of Cambridge for use on Unix systems connected to the Internet. In style it is similar to Smail 3, but its facilities are more extensive, and in particular it has options for verifying incoming sender and recipient addresses, for refusing mail from specified hosts, networks, or senders, and for controlling mail relaying. Exim is in production use at quite a few sites, some of which move hundreds of thousands of messages per day. Exiscan is compiled in to allow inbuilt scanning capability. See https://duncanthrax.net/exiscan-acl/ ---------------------------------------------------------------------Update Information: This erratum fixes two relatively minor security issues which were discovered in Exim in the last few weeks. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the names CAN-2005-0021 and CAN-2005-0022 to these, respectively. 1. The function host_aton() can overflow a buffer if it is presented with an illegal IPv6 address that has more than 8 components. 2. The second report described a buffer overflow in the function spa_base64_to_bits(), which is part of the code for SPA authentication. This code originated in the Samba project. The overflow can be exploited only if you are using SPAauthentication. ---------------------------------------------------------------------* Tue Jan 04 2005 David Woodhouse 4.43-1.FC3.1 - Fix buffer overflows (CAN-2005-0021, CAN-2005-0022) - Demonstrate SASL auth configuration in default config file - Enable TLS and provide certificate if necessary - Don't reject all GB2312 charset mail by default ---------------------------------------------------------------------This update can be downloaded from: f4cafadca104a85ff5f31cbf5ca4c4f1 SRPMS/exim-4.43-1.FC3.1.src.rpm 3412f5b4cf40ad504dbaf2b7e2fffa62 x86_64/exim-4.43-1.FC3.1.x86_64.rpm 1446c41e65cfd6f15ae60b969ab3d20c x86_64/exim-mon-4.43-1.FC3.1.x86_64.rpm e71be8446d9e4d250ca40a41c2d7b49a x86_64/exim-doc-4.43-1.FC3.1.x86_64.rpm 1d515c5be494e657333549f72f4621e2 x86_64/exim-sa-4.43-1.FC3.1.x86_64.rpm bcd320d0c2f88911a3ccc02b95cb2843 x86_64/debug/exim-debuginfo-4.43-1.FC3.1.x86_64.rpm 7c2205113fe3285a76b797748845548b i386/exim-4.43-1.FC3.1.i386.rpm 8227e5701319639057b951bc45bbecf8 i386/exim-mon-4.43-1.FC3.1.i386.rpm 3b7e2741f4208757e92ab2d228b1fe8a i386/exim-doc-4.43-1.FC3.1.i386.rpm 4e5cbfea028184d6710443a3c0e79c29 i386/exim-sa-4.43-1.FC3.1.i386.rpm 9c2c6e5d633104ca71bf80b062e9f0a2 i386/debug/exim-debuginfo-4.43-1.FC3.1.i386.rpm This update can also be installed with the Update Agent; you can launch the Update Agent with the 'up2date' command. -----------------------------------------------------------------------fedora-announce-list mailing list
