    Debian Bug     : 
    
    Several issues were discovered in libytnef, a library used to decode
    application/ms-tnef e-mail attachments. Multiple heap overflows,
    out-of-bound writes and reads, NULL pointer dereferences and infinite
    loops could be exploited by tricking a user into opening a maliciously
    crafted winmail.dat file.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1.5-6+deb8u1.
    
    For the upcoming stable (stretch) and unstable (sid) distributions,
    these problems have been fixed in version 1.9.2-1.
    
    We recommend that you upgrade your libytnef packages.
