CVE-2026-43996 OpenImageIO: Integer wraparound in bounds check of decode_pixel leads to out-of-bounds read in TGA paletted image decoder

OpenImageIO is a toolset for reading, writing, and manipulating image files of any image file format relevant to VFX / animation. Prior to 3.0.18.0 and 3.1.13.0, the bounds check in TGAInput::decodepixel computes k + palbytespp as unsigned 32-bit arithmetic. When k = 0xFFFFFFFC and palbytespp = 4...

CVE-2026-33020 libsixel: Integer Overflow in write_png_to_file() leads to Heap-based Buffer Overflow

libsixel is a SIXEL encoder/decoder implementation derived from kmiya's sixel. Versions 1.8.7 and prior contain an integer overflow which leads to a heap buffer overflow via sixelframeconverttorgb888 in frame.c, where allocation size and pointer offset computations for palettised images PAL1, PAL...

Fedora 15 : libpng10-1.0.55-1.fc15 (2011-8844)

This update fixes a 1-byte uninitialized memory reference in pngformatbuffer. It allows attackers to cause a denial of service crash via a malformed PNG image file that triggers an error that causes an out-of-bounds read when creating the error message. This is CVE-2011-2501. Also fixed in this...
