libpng: libpng: Information disclosure and denial of service via out-of-bounds read/write in Neon palette expansion

A flaw was found in libpng. A remote attacker could exploit an out-of-bounds read and write vulnerability in the ARM/AArch64 Neon-optimized palette expansion path. This occurs when processing a final partial chunk of 8-bit paletted rows without verifying sufficient input pixels, leading to...

libpng: libpng: Arbitrary code execution due to use-after-free vulnerability

A flaw was found in libpng, a library used for processing PNG Portable Network Graphics image files. This vulnerability arises from improper memory management where a heap-allocated buffer is aliased between internal data structures. When specific functions are called, a freed memory region can...

libpng: libpng: Denial of service and information disclosure via heap buffer over-read in png_image_finish_read

A flaw was found in libpng, a reference library for processing PNG Portable Network Graphics image files. A local attacker could exploit a heap buffer over-read vulnerability in the pngimagefinishread function by tricking a user into processing a specially crafted interlaced 16-bit PNG file with ...

libpng: LIBPNG out-of-bounds read in png_image_read_composite

An out of bounds read vulnerability has been discovered in libpng. This vulnerability is in libpng's simplified API allows reading up to 1012 bytes beyond the pngsRGBbase512 array when processing valid palette PNG images with partial transparency and gamma correction. The PNG files that trigger...

libpng: LIBPNG has a heap buffer overflow in png_set_quantize

A heap based buffer overflow flaw has been discovered in LibPNG. Prior to version 1.6.55, an out-of-bounds read vulnerability exists in the pngsetquantize API function. When the function is called with no histogram and the number of colors in the palette is more than twice the maximum supported b...

libpng: libpng: Information disclosure and denial of service via integer truncation in simplified write API

A flaw was found in libpng, a reference library for PNG Portable Network Graphics raster image files. An integer truncation vulnerability exists in the pngwriteimage16bit and pngwriteimage8bit simplified write API functions. A local attacker could exploit this flaw by providing a negative row...
