PHP

New PHP packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1,
and -current to fix a security issue with the PEAR XML_RPC class that
allows a remote attacker to run arbitrary PHP code. Sites that make
use of this PHP library should upgrade to the new PHP package right
away, or may instead upgrade the XML_RPC PEAR class with the following
command:

pear upgrade XML_RPC

More details about this issue may be found in the Common
Vulnerabilities and Exposures (CVE) database:

Here are the details from the Slackware 10.1 ChangeLog:

patches/packages/php-4.3.11-i486-2.tgz: Upgraded PEAR XML_RPC class.
This new PHP package fixes a PEAR XML_RPC vulnerability. Sites that use
this PEAR class should upgrade to the new PHP package, or as a minimal
fix may instead upgrade the XML_RPC PEAR class with the following command:
pear upgrade XML_RPC
(* Security fix *)
