<title>PHP: Multiple vulnerabilities</title>
|
|
<synopsis>
|
|
Several vulnerabilities were found and fixed in PHP, ranging from an
|
|
information leak and a safe_mode restriction bypass to a potential remote
|
|
execution of arbitrary code.

PHP is a general-purpose scripting language widely used to develop
|
|
web-based applications. It can run inside a web server using the
|
|
mod_php module or the CGI version of PHP, or can run stand-alone in a
|
|
CLI.

Stefan Esser and Marcus Boerger reported several different issues in
|
|
the unserialize() function, including serious exploitable bugs in the
|
|
way it handles negative references (CAN-2004-1019).
|
|
</p>
|
|
<p>
|
|
Stefan Esser also discovered that the pack() and unpack() functions are
|
|
subject to integer overflows that can lead to a heap buffer overflow
|
|
and a heap information leak. Finally, he found that the way
|
|
multithreaded PHP handles safe_mode_exec_dir restrictions can be
|
|
bypassed, and that various path truncation issues also allow to bypass
|
|
path and safe_mode restrictions.
|
|
</p>
|
|
<p>
|
|
Ilia Alshanetsky found a stack overflow issue in the exif_read_data()
|
|
function (CAN-2004-1065). Finally, Daniel Fabian found that addslashes
|
|
and magic_quotes_gpc do not properly escape null characters and that
|
|
magic_quotes_gpc contains a bug that could lead to one level directory
|
|
traversal.

<impact type="high">
|
|
<p>
|
|
These issues could be exploited by a remote attacker to retrieve web
|
|
server heap information, bypass safe_mode or path restrictions and
|
|
potentially execute arbitrary code with the rights of the web server
|
|
running a PHP application.
