CVE-2026-34757

LIBPNG is a reference library for use in applications that read, create, and manipulate PNG Portable Network Graphics raster image files. From 1.0.9 to before 1.6.57, passing a pointer obtained from pnggetPLTE, pnggettRNS, or pnggethIST back into the corresponding setter on the same...

ROS-20260401-73-0030

Vulnerability in libpng related to buffer copying without checking input size. Exploitation of the vulnerability could allow an attacker acting remotely to cause a denial of service...

CVE-2026-3713 pnggroup libpng pnm2png pnm2png.c do_pnm2png heap-based overflow

A flaw has been found in pnggroup libpng up to 1.6.55. Affected by this vulnerability is the function dopnm2png of the file contrib/pngminus/pnm2png.c of the component pnm2png. This manipulation of the argument width/height causes heap-based buffer overflow. The attack is restricted to local...

libpng: Buffer overflow vulnerabilities in png_get_PLTE/png_set_PLTE functions

It was discovered that the pnggetPLTE and pngsetPLTE functions of libpng did not correctly calculate the maximum palette sizes for bit depths of less than 8. In case an application tried to use these functions in combination with properly calculated palette sizes, this could lead to a buffer...

AZL-45078 CVE-2015-8126 affecting package fltk for versions less than 1.3.8-1

Multiple buffer overflows in the 1 pngsetPLTE and 2 pnggetPLTE functions in libpng before 1.0.64, 1.1.x and 1.2.x before 1.2.54, 1.3.x and 1.4.x before 1.4.17, 1.5.x before 1.5.24, and 1.6.x before 1.6.19 allow remote attackers to cause a denial of service application crash or possibly have...

DEBIAN-CVE-2014-0333

The pngpushreadchunk function in pngpread.c in the progressive decoder in libpng 1.6.x through 1.6.9 allows remote attackers to cause a denial of service infinite loop and CPU consumption via an IDAT chunk with a length of zero...

libpng DoS

The sPLT chunk handling code pngsetsPLT function in pngset.c in libpng 1.0.6 through 1.2.12 uses a sizeof operator on the wrong data type, which allows context-dependent attackers to cause a denial of service crash via malformed sPLT chunks that trigger an out-of-bounds read...
