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

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.
