Debian DSA-1282-1 : php4 - several vulnerabilities

high Nessus Plugin ID 25099

Synopsis

The remote Debian host is missing a security-related update.

Description

Several remote vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language, which may lead to the execution of arbitrary code. The Common Vulnerabilities and Exposures project identifies the following problems :

- CVE-2007-1286 Stefan Esser discovered an overflow in the object reference handling code of the unserialize() function, which allows the execution of arbitrary code if malformed input is passed from an application.

- CVE-2007-1380 Stefan Esser discovered that the session handler performs insufficient validation of variable name length values, which allows information disclosure through a heap information leak.

- CVE-2007-1521 Stefan Esser discovered a double free vulnerability in the session_regenerate_id() function, which allows the execution of arbitrary code.

- CVE-2007-1711 Stefan Esser discovered a double free vulnerability in the session management code, which allows the execution of arbitrary code.

- CVE-2007-1718 Stefan Esser discovered that the mail() function performs insufficient validation of folded mail headers, which allows mail header injection.

- CVE-2007-1777 Stefan Esser discovered that the extension to handle ZIP archives performs insufficient length checks, which allows the execution of arbitrary code.

Solution

Upgrade the PHP packages. Packages for the arm, m68k, mips and mipsel architectures are not yet available. They will be provided later.

For the oldstable distribution (sarge) these problems have been fixed in version 4.3.10-20.

For the stable distribution (etch) these problems have been fixed in version 4.4.4-8+etch2.
