CVE-2026-75538

A Signed Length Overflow in Erlang/OTP's inet TCP Driver Overflows the Receive Buffer Into BEAM VM Memory From an Unauthenticated Peer

An attacker that connects to an open Erlang TCP port that uses the inet driver with {packet,4} mode can use a signed overflow in an incorrect packet length calculation to overflow the receive buffer into the VM allocator area and beyond up to about 2 GB. This would easily trash the allocated block's allocator metadata footer, and the next block, if any, and most likely cause the BEAM VM to crash. Utilizing this with precision enough to achieve Remote Code Execution would be extremely unfeasible. This issue affects OTP from OTP 17.0 before OTP 27.3.4.17, OTP 28.5.0.6, and OTP 29.0.6, corresponding to erts from 6.0 before 15.2.7.13, 16.4.0.6, and 17.0.6. Whether OTP before OTP 17.0, corresponding to erts before 6.0, is affected is unknown.

CVE-2026-92248

Gimp: integer overflow when generating a thumbnail preview for a psd file

A flaw was found in the file-psd plugin in GIMP. When generating a thumbnail preview for a specially crafted PSD (Photoshop Document) image file, an integer overflow occurs during the multiplication of values from an embedded JPEG header. This leads to an undersized heap allocation, resulting in a heap-based buffer overflow when the image data is decoded. This buffer overflow corrupts adjacent heap objects, allowing for a controlled memory write that can result in an application crash or arbitrary code execution.

node-fontnik: integer-overflow heap out-of-bounds write in RenderSDF

node-fontnik is a library that delivers a range of glyphs rendered as SDFs (signed distance fields) in a protocol buffer. Prior to version 0.7.7, a crafted font could trigger a heap out-of-bounds write in RenderSDF (include/mapbox/glyph_foundry_impl.hpp). RenderSDF computed the SDF bitmap allocation size as buffered_width * buffered_height in 32-bit unsigned int. Glyph dimensions are derived from the uploaded font's outline bounding box with no upper bound, so a glyph large enough to make that product exceed 2³² wrapped to a small value. The buffer was then under-allocated while the render loop still wrote one byte per pixel, corrupting the heap (CWE-190 → CWE-787) and crashing the process. A 680-byte font is enough to drive FreeType to a 65536×65536 buffered glyph, wrapping the size to 0. This issue has been patched in version 0.7.7.

Multiple Vulnerabilities in SAP NetWeaver (Internet Graphics Service)

SAP NetWeaver (Internet Graphics Service) does not sufficiently validate certain input values within incoming requests. An unauthenticated user could send a specially crafted request causing the affected process to read beyond the declared values, resulting in repeated termination of the worker process. This results in a high impact on availability with no impact on integrity or confidentiality.

FFmpeg through 9.0.2 Heap Buffer Overflow via ProRes prores_ks Encoder

FFmpeg through 9.0.2 contains an integer overflow vulnerability in ff_prores_kostya_encode_init() that miscalculates frame_size_upper_bound using 32-bit arithmetic for large frame dimensions. Attackers can supply a high-resolution video transcoded with the prores_ks encoder, causing encode_frame() to write slices past an undersized packet buffer and corrupt heap memory.

FFmpeg through 9.0.2 Integer Overflow via dng_decode_tiles() in libavcodec/tiff.c

FFmpeg through 9.0.2 contains an integer overflow vulnerability in dng_decode_tiles() that allows attackers to leak uninitialized memory via crafted DNG tile dimensions. Attackers can set TileWidth or TileLength near INT_MAX so the tile loop never runs, outputting a frame exposing uninitialized or stale heap memory.

FFmpeg through 9.0.2 VVC Decoder Heap Out-of-Bounds Write via refs.c

FFmpeg through 9.0.2 contains an integer overflow vulnerability in the VVC decoder alloc_frame() function in libavcodec/vvc/refs.c that undersizes the reference picture list allocation on 32-bit builds. Attackers can supply a crafted VVC (H.266) file with a very large number of NAL units per access unit to trigger heap out-of-bounds writes and corrupt memory.

FFmpeg 9.0 through 9.0.2 Integer Overflow via FFV1 Vulkan Encoder Remap Buffer

FFmpeg 9.0 through 9.0.2 contains an integer overflow vulnerability in libavcodec/ffv1enc_vulkan.c that undersizes the float remap GPU buffer for large frames. Attackers can supply large GBRPF32 or GBRAPF32 images or videos that, when transcoded to FFV1 with the Vulkan encoder, trigger out-of-bounds GPU memory writes causing crashes or memory corruption.

FFmpeg before 8.1.3 and 9.x before 9.0.2 Heap Out-of-Bounds Write via APAC Decoder

FFmpeg before 8.1.3 and 9.x before 9.0.2 contains a heap out-of-bounds write vulnerability in the APAC decoder in libavcodec/apac.c caused by an unreset bitstream index. Attackers can supply a crafted APAC file whose growing bitstream_index triggers an integer overflow, bypassing the reallocation check so memcpy() corrupts heap memory or crashes the application.

FFmpeg through 9.0.2 Heap Buffer Overflow via cbs_jpeg_write_scan Integer Overflow

FFmpeg through 9.0.2 contains an integer overflow in cbs_jpeg_write_scan() in libavcodec/cbs_jpeg.c that causes a heap buffer overflow on 32-bit builds. Attackers can supply a crafted MJPEG/JPEG stream with a scan of 512 MiB or more, processed by CBS bitstream filters like filter_units, to corrupt the heap or crash the application.
