Mandriva Linux Security Advisory 2011-150 - Buffer overflow in the gopherToHTML function in gopher.cc in the Gopher reply parser in Squid 3.0 before 3.0.STABLE26, 3.1 before 3.1.15, and 3.2 before 3.2.0.11 allows remote Gopher servers to cause a denial of service or possibly have unspecified other impact via a long line in a response.

Mandriva Linux Security Advisory 2011-149 - Multiple vulnerabilities has been discovered and corrected in cyrus-imapd. Stack-based buffer overflow in the split_wildmats function in nntpd.c in nntpd in Cyrus IMAP Server before 2.3.17 and 2.4.x before 2.4.11 allows remote attackers to execute arbitrary code via a crafted NNTP command. Secunia Research has discovered a vulnerability in Cyrus IMAPd, which can be exploited by malicious people to bypass certain security restrictions. The vulnerability is caused due to an error within the authentication mechanism of the NNTP server, which can be exploited to bypass the authentication process and execute commands intended for authenticated users by sending an AUTHINFO USER command without a following AUTHINFO PASS command.

Red Hat Security Advisory 2011-1317-01 - The cyrus-imapd packages contain a high-performance mail server with IMAP, POP3, NNTP, and Sieve support. A buffer overflow flaw was found in the cyrus-imapd NNTP server, nntpd. A remote user able to use the nntpd service could use this flaw to crash the nntpd child process or, possibly, execute arbitrary code with the privileges of the cyrus user.
