[***** Start Debian Security Advisory DSA-670-1 *****] Debian Security Advisory DSA-670-1 emacs20 -- format string Date Reported: 08 Feb 2005 Affected Packages: emacs20 Vulnerable: Yes Security database references: In Mitre's CVE dictionary: CAN-2005-0100. More information: Max Vozeler discovered several format string vulnerabilities in the movemail utility of Emacs, the well-known editor. Via connecting to a malicious POP server an attacker can execute arbitrary code under the privileges of group mail. For the stable distribution (woody) these problems have been fixed in version 20.7-13.3. The unstable distribution (sid) does not contain an Emacs20 package anymore. We recommend that you upgrade your emacs packages.
