Detail
| 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. |
