Buffer overflow in the gdImageStringFTEx function in gdft.c in the 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.

Tetex 3.x uses an embedded copy of the gd source and may also be affected by this issue (CVE-2007-0455).

A buffer overflow in the open_sty function for makeindex in Tetex could allow user-assisted remote attackers to overwrite files and possibly execute arbitrary code via a long filename (CVE-2007-0650).

The updated packages have been patched to prevent these issues.

Updated PHP packages that fix several security issues are now available for Red Hat Enterprise Linux 5.

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 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 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)

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)

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

The remote NewStart CGSL host, running version MAIN 6.06, has gd packages installed that are affected by multiple vulnerabilities:

  - The GD Graphics Library (aka LibGD) 2.2.5 has a double free in the gdImage*Ptr() functions in     gd_gif_out.c, gd_jpeg.c, and gd_wbmp.c. NOTE: PHP is unaffected. (CVE-2019-6978)

  - The _gdGetColors function in gd_gd.c in PHP 5.2.11 and 5.3.x before 5.3.1, and the GD Graphics Library     2.x, does not properly verify a certain colorsTotal structure member, which might allow remote attackers     to conduct buffer overflow or buffer over-read attacks via a crafted GD file, a different vulnerability     than CVE-2009-3293. NOTE: some of these details are obtained from third party information. (CVE-2009-3546)

  - 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. (CVE-2007-0455)

  - The gdImageCreateFromXpm function in gdxpm.c in libgd, as used in PHP 5.4.26 and earlier, allows remote     attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted     color table in an XPM file. (CVE-2014-2497)

  - Integer signedness error in GD Graphics Library 2.1.1 (aka libgd or libgd2) allows remote attackers to     cause a denial of service (crash) or potentially execute arbitrary code via crafted compressed gd2 data,     which triggers a heap-based buffer overflow. (CVE-2016-3074)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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.

Buffer overflow in the gdImageStringFTEx function in gdft.c in the 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.

Libwmf uses an embedded copy of the gd source and may also be affected by this issue.

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)

(CVE-2007-0455)

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