CVE-2026-6385

FFmpeg vulnerability CVE-2026-6385: a signed integer overflow in the DVD subtitle parser’s fragment reassembly bounds checks can cause a heap out-of-bounds write when processing specially crafted MPEG-PS/VOB media with a malicious DVD subtitle stream. Impact includes denial of service via applica...

GHSA-P8XC-W3Q4-H64X OpenEXR: DWA Lossy Decoder Heap Out-of-Bounds Write

Summary The DWA lossy decoder constructs temporary per-component block pointers using signed 32-bit arithmetic. For a large enough width, the calculation overflows and later decoder stores operate on a wrapped pointer outside the allocated rowBlock backing store. This bug is reachable from the...

Out-of-bounds Write

Overview OpenEXR is a Python bindings for the OpenEXR image file format Affected versions of this package are vulnerable to Out-of-bounds Write. through the internalexrundopiz process. An attacker can cause out-of-bounds memory access, leading to potential memory corruption or process crash, by...

CVE-2026-35201

Discount is an implementation of John Gruber's Markdown markup language in C. From 1.3.1.1 to before 2.2.7.4, a signed length truncation bug causes an out-of-bounds read in the default Markdown parse path. Inputs larger than INTMAX are truncated to a signed int before entering the native parser,...

UBUNTU-CVE-2026-34380

OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From 3.2.0 to before 3.2.7, 3.3.9, and 3.4.9, a signed integer overflow exists in undopxr24impl in src/lib/OpenEXRCore/internalpxr24.c at line 377. The...

iccDEV 安全漏洞

CVE-2026-4775 Libtiff: libtiff: arbitrary code execution or denial of service via signed integer overflow in tiff file processing

A flaw was found in the libtiff library. A remote attacker could exploit a signed integer overflow vulnerability in the putcontig8bitYCbCr44tile function by providing a specially crafted TIFF file. This flaw can lead to an out-of-bounds heap write due to incorrect memory pointer calculations,...

kernel: tcp: fix a signed-integer-overflow bug in tcp_add_backlog()

A flaw was found in the Linux kernel’s TCP implementation in the function tcpaddbacklog. When calculating the maximum acceptable backlog for TCP sockets, the sum of the receive buffer skrcvbuf, the send buffer sksndbuf, and a fixed constant may exceed the maximum value of a signed integer due to...

CVE-2026-27799 ImageMagick has a heap Buffer Over-read in its DJVU image format handler

ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to versions 7.1.2-15 and 6.9.13-40, a heap buffer over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride ro...
