"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."
