php-net-ping - arbitrary code execution

It was discovered that php-net-ping, a PHP PEAR module to execute ping
independently of the Operating System, performs insufficient input
sanitising, which might be used to inject arguments (no CVE yet) or
execute arbitrary commands (CVE-2009-4024) on a system that uses
php-net-ping.

For the oldstable distribution (etch), this problem has been fixed in
version 2.4.2-1+etch1.

For the stable distribution (lenny), this problem has been fixed in
version 2.4.2-1+lenny1.

For the testing distribution (squeeze), this problem will be fixed
soon.

For the unstable distribution (sid), this problem has been fixed in
version 2.4.2-1.1.

We recommend that you upgrade your php-net-ping packages.
