New php5 packages are available for Slackware 10.2, 11.0, and -current to fix security issues. PHP5 was considered a test package in Slackware 10.2, and an "extra" package in Slackware 11.0. If you are currently running PHP4 you may wish to stick with that, as upgrading to PHP5 will probably require changes to your system's configuration and/or web code.

More details about the issues affecting Slackware's PHP5 may be found in the Common Vulnerabilities and Exposures (CVE) database:

http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-1900
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2756
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-2872

One CVE-issued vulnerability (CVE-2007-1887) does not affect Slackware as
we do not ship an unbundled sqlite2 library.



Here are the details from the Slackware 11.0 ChangeLog:
+--------------------------+
extra/php5/php-5.2.3-i486-1_slack11.0.tgz:
Upgraded to php-5.2.3.
Here's some basic information about the release from php.net:
"This release continues to improve the security and the stability of the
5.X branch as well as addressing two regressions introduced by the
previous 5.2 releases. These regressions relate to the timeout handling
over non-blocking SSL connections and the lack of HTTP_RAW_POST_DATA in
certain conditions. All users are encouraged to upgrade to this release."
