"The sscanf() function did not properly check array boundaries. In
applications which use sscanf() with argument swapping, a remote
attacker could potentially exploit this to crash the affected web
application or even execute arbitrary code with the application's
privileges. (CVE-2006-4020)

The file_exists() and imap_reopen() functions did not perform proper
open_basedir and safe_mode checks which could allow local scripts to
bypass intended restrictions. (CVE-2006-4481)

On 64 bit systems the str_repeat() and wordwrap() functions did not
properly check buffer boundaries. Depending on the application, this
could potentially be exploited to execute arbitrary code with the
applications' privileges. This only affects the amd64 and sparc
platforms. (CVE-2006-4482)

A buffer overflow was discovered in the LWZReadByte_() function of the
GIF image file parser. By tricking a PHP application into processing a
specially crafted GIF image, a remote attacker could exploit this to
execute arbitrary code with the application's privileges.
(CVE-2006-4484).

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."
