Several security related problems have been found in PHP4, the
server-side, HTML-embedded scripting language. The Common
Vulnerabilities and Exposures project identifies the following
problems:
CVE-2005-1751
Eric Romang discovered insecure temporary files in the shtool
utility shipped with PHP that can exploited by a local attacker to
overwrite arbitrary files. Only this vulnerability affects
packages in oldstable.
CVE-2005-1921
GulfTech has discovered that PEAR XML_RPC is vulnerable to a
remote PHP code execution vulnerability that may allow an attacker
to compromise a vulnerable server.
CVE-2005-2498
Stefan Esser discovered another vulnerability in the XML-RPC
libraries that allows injection of arbitrary PHP code into eval()
statements.
For the testing distribution (etch) this is fixed in version 4.3.10-16etch1
For the unstable distribution (sid) this is fixed in version 4.4.0-2
This upgrade is recommended if you use php4.
If you have the secure testing lines in your sources.list, you can update by running this command as root:
apt-get update && apt-get upgrade
To use the Debian testing security archive, add the following lines to your /etc/apt/sources.list:
deb http://secure-testing-mirrors.debian.net/debian-secure-testing etch/security-updates main contrib non-free
deb-src http://secure-testing-mirrors.debian.net/debian-secure-testing etch/security-updates main contrib non-free
