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. 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. For the testing distribution (wheezy), this problem will be fixed soon. For the unstable distribution (sid), this problem has been fixed in cyrus-imapd-2.4 version 2.4.12-1. We recommend that you upgrade your cyrus-imapd-2.2 packages.
