    Debian Bug     : 862442
    
    It was discovered that tnef, a tool used to unpack MIME attachments of
    type "application/ms-tnef", did not correctly validate its input. An
    attacker could exploit this by tricking a user into opening a
    malicious attachment, which would result in a denial-of-service by
    application crash.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 1.4.9-1+deb8u3.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.4.12-1.2.
    
    We recommend that you upgrade your tnef packages.
