PHP (SSA:2005-242-02)

New PHP packages are available for Slackware 8.1, 9.0, 9.1, 10.0, 10.1, and -current to fix security issues. PHP has been relinked with the shared PCRE library to fix an overflow issue with PHP's builtin PRCE code, and PEAR::XMLRPC has been upgraded to version 1.4.0 which eliminates the eval() function. The eval() function is believed to be insecure as implemented, and would be difficult to secure.

Note that these new packages now require that the PCRE package be installed, so be sure to get the new package from the patches/packages/directory if you don't already have it. A new version of this (6.3) was also issued today, so be sure that is the one you install.

More details about these issues 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-i486-3.tgz: Relinked with the system PCRE library,
as the builtin library has a buffer overflow that could be triggered by the
processing of a specially crafted regular expression.
Note that this change requires the pcre package to be installed.

(* Security fix *)
Upgraded PEAR::XMLRPC to version 1.4.0, which eliminates the use of the
insecure eval() function.
