    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.
