CVE-2007-2756

The gdPngReadData function in libgd 2.0.34 allows user-assisted attackers to cause a denial of service CPU consumption via a crafted PNG image with truncated data, which causes an infinite loop in the pngreadinfo function in libpng...

CVE-2007-2756

The CVE-2007-2756 issue affects the GD library (libgd) with version 2.0.34, where gdPngReadData can enter an infinite loop in png_read_info when processing a crafted PNG with truncated data. This leads to CPU exhaustion (DoS) and is described as user-assisted. Demonstrated vulnerability context c...

PHP <= 5.2.1 wbmp file handling integer overflow

There is an integer overflow in PHP in ext/gd/libgd/wbmp.c in the function readwbmp. If large enough values are specified for wbmp image height and/or width, so that widthheight 2^32, an integer overflow occurs on the following line if wbmp-bitmap = int safeemallocwbmp-width wbmp-height, sizeofin...

CVE-2007-1001

Multiple integer overflows in the 1 createwbmp and 2 readwbmp functions in wbmp.c in the GD library libgd in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allow context-dependent attackers to execute arbitrary code via Wireless Bitmap WBMP images with large width or height values...

Mandrake Linux Security Advisory : libwmf (MDKSA-2006:114-1)

Multiple buffer overflows in the gd graphics library libgd 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function. CVE-2004-0941 Integer overflows were reported in the GD Graphics...

Mandrake Linux Security Advisory : tetex (MDKSA-2006:113)

Integer overflows were reported in the GD Graphics Library libgd 2.0.28, and possibly other versions. These overflows allow remote attackers to cause a denial of service and possibly execute arbitrary code via PNG image files with large image rows values that lead to a heap-based buffer overflow ...

Ubuntu 4.10 : libgd vulnerabilities (USN-33-1)

CAN-2004-0990 described several buffer overflows which had been discovered in libgd's PNG handling functions. Another update is required because the update from USN-21-1 was not sufficient to prevent every possible attack. If an attacker tricks a user into loading a malicious PNG or XPM image, th...

Ubuntu 4.10 : libgd vulnerabilities (USN-21-1)

Several buffer overflows have been discovered in libgd's PNG handling functions. If an attacker tricked a user into loading a malicious PNG image, they could leverage this into executing arbitrary code in the context of the user opening image. Most importantly, this library is commonly used in PH...

gd: additional overflows

Multiple buffer overflows in the gd graphics library libgd 2.0.21 and earlier may allow remote attackers to execute arbitrary code via malformed image files that trigger the overflows due to improper calls to the gdMalloc function, a different set of vulnerabilities than CVE-2004-0990...
