| Description: | Summary:
The remote host is missing an update for the Debian 'php5' package(s) announced via the DSA-2195-1 advisory.
Vulnerability Insight:
Stephane Chazelas discovered that the cronjob of the PHP 5 package in Debian suffers from a race condition which might be used to remove arbitrary files from a system (CVE-2011-0441).
When upgrading your php5-common package take special care to accept the changes to the /etc/cron.d/php5 file. Ignoring them would leave the system vulnerable.
For the oldstable distribution (lenny), this problem has been fixed in version 5.2.6.dfsg.1-1+lenny10.
For the stable distribution (squeeze), this problem has been fixed in version 5.3.3-7+squeeze1.
