    Posted ByLinuxSecurity Advisories
    There are several buffer overflows and a broken boundary check within fetchmail. If fetchmail is running in multidrop mode these flaws can be used by remote attackers to crash it or to execute arbitrary code under the user id of the user running fetchmail. Depending on the configuration this even allows a remote rootcompromise.

    Package        : fetchmail, fetchmail-ssl
    Vulnerability  : buffer overflows
    Problem-Type   : remote
    Debian-specific: no
    
    Stefan Esser discovered several buffer overflows and a broken boundary
    check within fetchmail.  If fetchmail is running in multidrop mode
    these flaws can be used by remote attackers to crash it or to execute
    arbitrary code under the user id of the user running fetchmail.
    Depending on the configuration this even allows a remote root
    compromise.
    
    These problems have been fixed in version 5.9.11-6.1 for both
    fetchmail and fetchmail-ssl for the current stable distribution
    (woody), in version 5.3.3-4.2 for fetchmail for the old stable
    distribution (potato) and in version 6.1.0-1 for both fetchmail and
    fetchmail-ssl for the unstable distribution (sid).  There are no
    fetchmail-ssl packages for the old stable distribution (potato) and
    thus no updates.
    
    We recommend that you upgrade your fetchmail packages immediately.
    
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    
    You may use an automated update by adding the resources from the
    footer to the proper configuration.
