CVE-2007-2756 1 Libgd 1 Libgd 2025-04-09 4.3 MEDIUM N/A
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 png_read_info function in libpng.
CVE-2009-3546 2 Libgd, Php 2 Gd Graphics Library, Php 2025-04-09 9.3 HIGH N/A
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-2007-3474 1 Libgd 1 Gd Graphics Library 2025-04-09 2.6 LOW N/A
Multiple unspecified vulnerabilities in the GIF reader in the GD Graphics Library (libgd) before 2.0.35 have unspecified impact and user-assisted remote attack vectors.
CVE-2007-3477 1 Libgd 1 Gd Graphics Library 2025-04-09 5.0 MEDIUM N/A
The (a) imagearc and (b) imagefilledarc functions in GD Graphics Library (libgd) before 2.0.35 allow attackers to cause a denial of service (CPU consumption) via a large (1) start or (2) end angle degree value.
CVE-2021-40812 1 Libgd 1 Libgd 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
The GD Graphics Library (aka LibGD) through 2.3.2 has an out-of-bounds read because of the lack of certain gdGetBuf and gdPutBuf return value checks.
CVE-2021-40145 1 Libgd 1 Libgd 2024-11-21 5.0 MEDIUM 7.5 HIGH
gdImageGd2Ptr in gd_gd2.c in the GD Graphics Library (aka LibGD) through 2.3.2 has a double free. NOTE: the vendor's position is "The GD2 image format is a proprietary image format of libgd. It has to be regarded as being obsolete, and should only be used for development and testing purposes.
CVE-2021-38115 1 Libgd 1 Libgd 2024-11-21 4.3 MEDIUM 6.5 MEDIUM
read_header_tga in gd_tga.c in the GD Graphics Library (aka LibGD) through 2.3.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted TGA file.
CVE-2019-6978 3 Canonical, Debian, Libgd 3 Ubuntu Linux, Debian Linux, Libgd 2024-11-21 7.5 HIGH 9.8 CRITICAL
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.
