    Package : php5

    The previous update for php5, DSA-3074-1, introduced regression in the sessionclean cron script. The change was intended to fix a potential
    symlink attack using filenames including the NULL character (Debian bug #766147), but depended on sed package version too recent, not in Wheezy.

    This update reverts the fix, so people are advised to keep kernel
    symlink protection (sysctl fs.protected_symlinks=1) enabled as it is by
    default on Wheezy, which is enough to prevent successful exploitation.

    For the stable distribution (wheezy), this problem has been fixed in
    version 5.4.35-0+deb7u2.

    We recommend that you upgrade your php5 packages.
