    Debian Bug     : 763780
    
    Guillem Jover discovered that the changelog retrieval functionality in
    apt-get used temporary files in an insecure way, allowing a local user
    to cause arbitrary files to be overwritten.
    
    This vulnerability is neutralized by the fs.protected_symlinks setting in
    the Linux kernel, which is enabled by default in Debian 7 Wheezy and up.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 0.9.7.9+deb7u6.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.0.9.2.
    
    We recommend that you upgrade your apt packages.
