gimp: GIMP APNG loader heap-buffer-overflow when fcTL width exceeds IHDR width (file-png.c)

A heap-buffer-overflow vulnerability exists in the APNG Animated PNG file loader of GIMP. This flaw occurs when the fcTL width exceeds the IHDR width, leading to pixel data being written past the end of a heap allocation. Additionally, a heap-based buffer overflow exists in the DDS plug-in due to...

Heap-based Buffer Overflow

Overview Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the decodemaskimage function. An attacker can cause a heap buffer overflow by providing a crafted HEIF file containing a mask image where the iloc extent exceeds the allocated pixel buffer, leading to...

CVE-2026-32741

libheif is a HEIF and AVIF file format decoder and encoder. Versions 1.21.2 and below contain a heap buffer overflow in MaskImageCodec::decodemaskimage. When decoding a HEIF file containing a mask image mski, the function copies the full iloc extent data into a pixel buffer using memcpydst,...

CVE-2026-40492

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit 36aa5c7ec8a2bb35f6fb867a1177a6f141156b02, the XWD codec resolves pixel format based on pixmapdepth but the byte-swap code uses bitsperpixel independently. When...

Out-of-bounds Write

Overview Affected versions of this package are vulnerable to Out-of-bounds Write in the XWD decoder when there is a type confusion between bitsperpixel and pixmapdepth during the byte-swap process. An attacker can achieve arbitrary code execution or cause a denial of service by providing a crafte...

CVE-2026-40493 SAIL has heap buffer overflow in PSD decoder — bpp mismatch in LAB 16-bit mode

SAIL is a cross-platform library for loading and saving images with support for animation, metadata, and ICC profiles. Prior to commit c930284445ea3ff94451ccd7a57c999eca3bc979, the PSD codec computes bytes-per-pixel bpp from raw header fields channels depth, but the pixel buffer is allocated base...

CVE-2026-40493

SAIL PSD decoder in LAB mode (3 channels, 16-bit depth) suffers a heap buffer overflow due to a bpp mismatch: bytes-per-pixel is computed as (channelsdepth) but the allocated buffer uses the resolved pixel format (BPP40_CIE_LAB yields 5 bytes/pixel while 3 16 would imply 6). This causes every pix...

CVE-2026-40492

SAIL’s CVE-2026-40492 describes a heap buffer overflow in the XWD decoder caused by a mismatch: when pixmap_depth=8, the code uses bits_per_pixel=32 for byte-swapping, leading to memory access beyond the 1-byte/pixel buffer. The issue affects versions prior to the patch 36aa5c7ec8a2bb35f6fb867a11...
