    Package        : p7zip
    CVE ID         : CVE-2015-1038
    Debian Bug     : 774660
    
    Alexander Cherepanov discovered that p7zip is susceptible to a
    directory traversal vulnerability.  While extracting an archive, it
    will extract symlinks and then follow them if they are referenced in
    further entries.  This can be exploited by a rogue archive to write
    files outside the current directory.
    
    For the oldstable distribution (wheezy), this problem has been fixed
    in version 9.20.1~dfsg.1-4+deb7u1.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 9.20.1~dfsg.1-4.1+deb8u1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 9.20.1~dfsg.1-4.2.
    
    We recommend that you upgrade your p7zip packages.
