Security update : PHP 5.3.10

Guillaume Plessis — Fri, 03 Feb 2012 01:25:52 +0000

A few hours ago, PHP 5.3.10 has been released by the PHP Group. It’s an important security update for PHP 5.3.9 users : Stefan Esser discovered a remotely exploitable bug, introduced with PHP 5.3.9′s max_input_vars directive (CVE-2012-0830). You really should upgrade as soon as possible.

Packages of PHP 5.3.10 are now available for Debian 6.0 “Squeeze” on both amd64 and i386 architectures.
Those for Debian 5.0 “Lenny” (certainly the last ones before the end of its security support on Feb 6th) are coming in a few hours.

Advisory : buffer overflow in php5-suhosin

Guillaume Plessis — Tue, 24 Jan 2012 15:02:26 +0000

A few days ago, Stefan Esser discovered a buffer overflow in the “transparent cookie encryption stack” of the Suhosin extension. Here is the full advisory.

If you previously installed the php5-suhosin package, you should upgrade to its fixed new version (0.9.33) by running :

apt-get update
apt-get install --reinstall php5-suhosin

No more Debian 5.0 “Lenny” support after february 2012

Guillaume Plessis — Wed, 07 Dec 2011 23:10:37 +0000

The Debian project has announced in a security advisory (DSA-2360-1) that the security support for Debian GNU/Linux 5.0 “Lenny” will be terminated in february 2012 :

This is an advance notice that security support for Debian GNU/Linux 5.0
(code name "lenny") will be terminated in two months.

The Debian project released Debian GNU/Linux 6.0 alias "squeeze" on the
6th of February 2011. Users and distributors have been given a one-year
timeframe to upgrade their old installations to the current stable
release. Hence, the security support for the old release of 5.0 is going
to end on the 6th of February 2012 as previously announced.

Previously announced security updates for the old release will continue
to be available on security.debian.org.

FYI, Dotdeb will follow this decision and no new packages will be available for Debian 5.0 after february 2012. Don’t be sad, this will give me some free time to focus on PHP 5.4 packages and some more cool tools.

It’s now time to upgrade your last Lenny boxes…

PHP 5.3.6 is available

Guillaume Plessis — Sat, 09 Apr 2011 16:07:34 +0000

On March 17th, the PHP Group released PHP 5.3.6. This maintainance release, that focuses on security, is now available on Dotdeb for Debian 6.0 “Squeeze” in amd64 and i386 flavours.

The compatibility with the official Debian packages has been improved and you (especially the FPM users) should really take care of some important changes that I made :

the intl extension is now built in a separate package : php5-intl
the FPM binary is now /usr/sbin/php5-fpm (previously /usr/bin/php5-fpm)
the FPM configuration file is now /etc/php5/fpm/php-fpm.conf (previously /etc/php5/fpm/php5-fpm.conf)
the FPM pools have to be moved to /etc/php5/fpm/pool.d/ (previously /etc/php5/fpm/pools/)

As usual, please read the Changelog before upgrading.

Note : The PHP 5.3.6 packages for Debian 5.0 “Lenny” should be released soon.
Update : the PHP 5.3.6 packages for Debian 5.0 “Lenny” are now available on http://php53.dotdeb.org/

You really should upgrade to PHP 5.3.5 or 5.2.17

Guillaume Plessis — Fri, 07 Jan 2011 10:53:42 +0000

A few days after releasing PHP 5.3.4 and PHP 5.2.16, the PHP group announced an important security update with PHP 5.3.5 and PHP 5.2.17 :

This release resolves a critical issue, reported as PHP bug #53632 and CVE-2010-4645, where conversions from string to double might cause the PHP interpreter to hang on systems using x87 FPU registers.

The problem is known to only affect x86 32-bit PHP processes, regardless of whether the system hosting PHP is 32-bit or 64-bit. You can test whether your system is affected by running this script from the command line.

All users of PHP are strongly advised to update to these versions immediately.

The Dotdeb packages for Debian “Lenny” 5.0 are now available. You really should upgrade.

Packages of MySQL 5.1.53 are available for Lenny… and Squeeze!

Guillaume Plessis — Sun, 05 Dec 2010 22:50:38 +0000

MySQL 5.1.53 packages for Debian 5.0 « Lenny » are now available on Dotdeb in amd64/i386 flavours. Please note that they’re available as preview for Squeeze too.

Upgrade to MySQL 5.1.51! It fixes a DoS vulnerability

Guillaume Plessis — Tue, 05 Oct 2010 21:14:32 +0000

MySQL versions prior to 5.1.51 (including 5.1.50) suffer from a vulnerability in the processing of arguments passed to the LEAST()or GREATEST() functions. This issue could be exploited by a malicious user to cause a server crash, leading to a DoS condition.

You really should upgrade your Lenny servers (amd64 or i386) with the new packages of MySQL 5.1.51 from Dotdeb. As usual, don’t forget to read the Changelog before upgrading.

Dotdeb packages are now signed!

Guillaume Plessis — Sun, 11 Jul 2010 15:35:51 +0000

After many requests from several users and after many months of promise, the Dotdeb repositories are GPG-signed. Yes, you can now get rid of the annoying “WARNING: The following packages cannot be authenticated!” message!

Waiting for a dotdeb-keyring package, you just have to get the key and add it to your trusted keys’ keyring :

gpg --keyserver keys.gnupg.net --recv-key 89DF5277
gpg -a --export 89DF5277 | sudo apt-key add -

I hope you’ll enjoy it.

MySQL 5.1.47, a security-focused release, is available

Guillaume Plessis — Tue, 25 May 2010 16:38:01 +0000

MySQL 5.1.47 is now available on Dotdeb for your Lenny servers, in amd64 and i386 flavours.

This is a security-oriented release that fixes some serious flaws… Please read full changelog for more information.

Please also note that the InnoDB plugin has been upgraded to version 1.0.8 and is now considered of General Availability quality. Feel free to use it for a performance boost.

May is the month of PHP security

Guillaume Plessis — Tue, 04 May 2010 12:26:21 +0000

According to Stefan Esser, author of the Suhosin patch, May 2010 will be the “Month of PHP Security” :

This initiative continues the effort of Hardened-PHP’s Month of PHP Bugs in 2007 to improve the security of PHP and the PHP ecosystem by disclosing vulnerabilities in PHP and PHP applications on the one hand and on the other hand by publishing articles and tools that help PHP application developers to develop more secure PHP applications.

You’ll find more information on the MoPS website and you can follow its twitter account to discover each vulnerability as soon as it’s reported.
