Synopsis
The remote Debian host is missing a security-related update.Description
Multiple security issues have been discovered in cyrus-imapd, a highly scalable mail system designed for use in enterprise environments. The Common Vulnerabilities and Exposures project identifies the following problems :- CVE-2011-3208 Coverity discovered a stack-based buffer overflow in the NNTP server implementation (nttpd) of cyrus-imapd. An attacker can exploit this flaw via several crafted NNTP commands to execute arbitrary code.
- CVE-2011-3372 Stefan Cornelius of Secunia Research discovered that the command processing of the NNTP server implementation (nttpd) of cyrus-imapd is not properly implementing access restrictions for certain commands and is not checking for a complete, successful authentication. An attacker can use this flaw to bypass access restrictions for some commands and, e.g. exploit CVE-2011-3208 without proper authentication.
Solution
Upgrade the cyrus-imapd-2.2 packages.For the oldstable distribution (lenny), this problem has been fixed in version 2.2_2.2.13-14+lenny5.
For the stable distribution (squeeze), this problem has been fixed in version 2.2_2.2.13-19+squeeze2.
