    Package        : openafs
    CVE ID         : CVE-2014-0159
    
    Michael Meffie discovered that in OpenAFS, a distributed filesystem,
    an attacker with the ability to connect to an OpenAFS fileserver can
    trigger a buffer overflow, crashing the fileserver, and potentially
    permitting the execution of arbitrary code.
    
    In addition, this update addresses a minor denial of service issue:
    the listerer thread of the server will hang for about one second when
    receiving an invalid packet, giving the opportunity to slow down
    the server to an unusable state by sending such packets.
    
    For the oldstable distribution (squeeze), this problem has been fixed
    in version 1.4.12.1+dfsg-4+squeeze3.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.6.1-3+deb7u2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.6.7-1.
    
    We recommend that you upgrade your openafs packages.
