Vulnerability Assessment Details
Check for the version of the php packages
Detailed Explanation for this Vulnerability Assessment
Updated php packages that fix various security issues and bugs are now
available for Red Hat Enterprise Linux 3.
PHP is an HTML-embedded scripting language commonly used with the Apache
HTTP Web server.
Flaws including possible information disclosure, double free, and negative
reference index array underflow were found in the deserialization code of
PHP. PHP applications may use the unserialize function on untrusted user
data, which could permit a remote attacker to gain access to memory or
potentially execute arbitrary code. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1019 to
A flaw in the exif extension of PHP was found which lead to a stack
overflow. A possible hacker could create a carefully crafted image file in such
a way that if parsed by a PHP script using the exif extension it could
cause a crash or potentially execute arbitrary code. The Common
Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name
CVE-2004-1065 to this issue.
An information disclosure bug was discovered in the parsing of "GPC"
variables in PHP (query strings or cookies, and POST form data). If
particular scripts used the values of the GPC variables, portions of the
memory space of an httpd child process could be revealed to the client.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2004-0958 to this issue.
A file access bug was discovered in the parsing of "multipart/form-data"
forms, used by PHP scripts which permit file uploads. In particular
configurations, some scripts could permit a malicious client to upload files
to an arbitrary directory where the "apache" user has write access. The
Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned
the name CVE-2004-0959 to this issue.
Flaws were found in shmop_write, pack, and unpack PHP functions. These
functions are not normally passed user supplied data, so would require a
malicious PHP script to be exploited. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CVE-2004-1018 to
Various issues were discovered in the use of the "select" system call in
PHP, which could be triggered if PHP is used in an Apache configuration
where the number of open files (such as virtual host log files) exceeds the
default process limit of 1024. Workarounds are now included for some of
The "phpize" shell script included in PHP can be used to build third-party
extension modules. A build issue was discovered in the "phpize" script on
some 64-bit platforms which prevented correct operation.
The "pcntl" extension module is now enabled in the command line PHP
interpreter, /usr/bin/php. This module enables process control features
such as "fork" and "kill" from PHP scripts.
Users of PHP should upgrade to these updated packages, which contain fixes
for these issues.
