    Package        : apt
    CVE ID         : CVE-2016-1252
    
    Jann Horn of Google Project Zero discovered that APT, the high level
    package manager, does not properly handle errors when validating
    signatures on InRelease files. An attacker able to man-in-the-middle
    HTTP requests to an apt repository that uses InRelease files
    (clearsigned Release files), can take advantage of this flaw to
    circumvent the signature of the InRelease file, leading to arbitrary
    code execution.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 1.0.9.8.4.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.4~beta2.
    
    We recommend that you upgrade your apt packages.
