From Red Hat Security Advisory 2007:0155 :

Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having important security impact by the Red Hat Security Response Team.

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Web server.

A denial of service flaw was found in the way PHP processed a deeply nested array. A remote attacker could cause the PHP interpreter to crash by submitting an input variable with a deeply nested array.
(CVE-2007-1285)

A flaw was found in the way PHP's unserialize() function processed data. If a remote attacker was able to pass arbitrary data to PHP's unserialize() function, they could possibly execute arbitrary code as the apache user. (CVE-2007-1286)

A flaw was found in the way the mbstring extension set global variables. A script which used the mb_parse_str() function to set global variables could be forced to enable the register_globals configuration option, possibly resulting in global variable injection.
(CVE-2007-1583)

A double free flaw was found in PHP's session_decode() function. If a remote attacker was able to pass arbitrary data to PHP's session_decode() function, they could possibly execute arbitrary code as the apache user. (CVE-2007-1711)

A flaw was discovered in the way PHP's mail() function processed header data. If a script sent mail using a Subject header containing a string from an untrusted source, a remote attacker could send bulk e-mail to unintended recipients. (CVE-2007-1718)

A heap based buffer overflow flaw was discovered in PHP's gd extension. A script that could be forced to process WBMP images from an untrusted source could result in arbitrary code execution.
(CVE-2007-1001)

A buffer over-read flaw was discovered in PHP's gd extension. A script that could be forced to write arbitrary string using a JIS font from an untrusted source could cause the PHP interpreter to crash.
(CVE-2007-0455)

Users of PHP should upgrade to these updated packages which contain backported patches to correct these issues.

Multiple issues were discovered in the gd GIF image-handling code. A carefully-crafted GIF file could cause a crash or possibly execute code with the privileges of the application using the gd library.
(CVE-2006-4484, CVE-2007-3475, CVE-2007-3476)

An integer overflow was discovered in the gdImageCreateTrueColor() function, leading to incorrect memory allocations. A carefully crafted image could cause a crash or possibly execute code with the privileges of the application using the gd library. (CVE-2007-3472)

A buffer over-read flaw was discovered. This could cause a crash in an application using the gd library to render certain strings using a JIS-encoded font. (CVE-2007-0455)

A flaw was discovered in the gd PNG image handling code. A truncated PNG image could cause an infinite loop in an application using the gd library. (CVE-2007-2756)

A flaw was discovered in the gd X BitMap (XBM) image-handling code. A malformed or truncated XBM image could cause a crash in an application using the gd library. (CVE-2007-3473)

Several vulnerabilities have been discovered in libgd2, a library for programmatic graphics creation and manipulation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2007-0455     Kees Cook discovered a buffer overflow in libgd2's font     renderer. An attacker could cause denial of service     (application crash) and possibly execute arbitrary code     via a crafted string with a JIS encoded font. This issue     only affects the oldstable distribution (etch).

  - CVE-2009-3546     Tomas Hoger discovered a boundary error in the     '_gdGetColors()' function. An attacker could conduct a     buffer overflow or buffer over-read attacks via a     crafted GD file.

Updated gd packages that fix multiple security issues are now available for Red Hat Enterprise Linux 4 and 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The gd package contains a graphics library used for the dynamic creation of images such as PNG and JPEG.

Multiple issues were discovered in the gd GIF image-handling code. A carefully-crafted GIF file could cause a crash or possibly execute code with the privileges of the application using the gd library.
(CVE-2006-4484, CVE-2007-3475, CVE-2007-3476)

An integer overflow was discovered in the gdImageCreateTrueColor() function, leading to incorrect memory allocations. A carefully crafted image could cause a crash or possibly execute code with the privileges of the application using the gd library. (CVE-2007-3472)

A buffer over-read flaw was discovered. This could cause a crash in an application using the gd library to render certain strings using a JIS-encoded font. (CVE-2007-0455)

A flaw was discovered in the gd PNG image handling code. A truncated PNG image could cause an infinite loop in an application using the gd library. (CVE-2007-2756)

A flaw was discovered in the gd X BitMap (XBM) image-handling code. A malformed or truncated XBM image could cause a crash in an application using the gd library. (CVE-2007-3473)

Users of gd should upgrade to these updated packages, which contain backported patches which resolve these issues.

A buffer overflow was discovered in libgd2's font renderer. By tricking an application using libgd2 into rendering a specially crafted string with a JIS encoded font, a remote attacker could read heap memory or crash the application, leading to a denial of service.
(CVE-2007-0455)

Xavier Roche discovered that libgd2 did not correctly validate PNG callback results. If an application were tricked into processing a specially crafted PNG image, it would monopolize CPU resources. Since libgd2 is often used in PHP and Perl web applications, this could lead to a remote denial of service. (CVE-2007-2756).

The updated packages have been patched to prevent these issues.

The remote host is running a version of PHP lower than 4.4.7 or 5.2.2.  This version is vulnerable to a number of remote issues.  At least one of these issues is related to a buffer overflow attack.  An attacker exploiting these flaws would be able to impact confidentiality, integrity, and availability. 

According to its banner, the version of PHP installed on the remote host is older than 4.4.7 / 5.2.2.  Such versions may be affected by several issues, including buffer overflows in the GD library.

PHP 5.2.0 and 4.4 allows local users to bypass safe_mode and open_basedir restrictions via a malicious path and a null byte before a ';' in a session_save_path argument, followed by an allowed path, which causes a parsing inconsistency in which PHP validates the allowed path but sets session.save_path to the malicious path.
(CVE-2006-6383)

Buffer overflow in the gdImageStringFTEx function in gdft.c in GD Graphics Library 2.0.33 and earlier allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a crafted string with a JIS encoded font.
