Ubuntu 5.10 / 6.06 LTS / 6.10 : php5 vulnerability (USN-375-1)

2007-11-10T00:00:00
ID UBUNTU_USN-375-1.NASL
Type nessus
Reporter Tenable

Description

Stefan Esser discovered two buffer overflows in the htmlentities() and htmlspecialchars() functions. By supplying specially crafted input to PHP applications which process that input with these functions, a remote attacker could potentially exploit this to execute arbitrary code with the privileges of the application. (CVE-2006-5465)

This update also fixes bugs in the chdir() and tempnam() functions, which did not perform proper open_basedir checks. This could allow local scripts to bypass intended restrictions.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
