    CVE ID         : CVE-2017-6891
    Debian Bug     : 863186
    
    Jakub Jirasek of Secunia Research discovered that libtasn1, a library
    used to handle Abstract Syntax Notation One structures, did not
    properly validate its input. This would allow an attacker to cause a
    crash by denial-of-service, or potentially execute arbitrary code, by
    tricking a user into processing a maliciously crafted assignments
    file.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 4.2-3+deb8u3.
    
    We recommend that you upgrade your libtasn1-6 packages.
