    Package : cyrus-imapd-2.2
    Vulnerability : multiple
    Problem type : remote
    Debian-specific: no
    Debian bug : none
    CVE IDs : CVE-2011-3372 CVE-2011-3208

    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.


    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.
