ImageMagick Has Signed Integer Overflow in SIXEL Decoder, Leading to Memory Corruption

A signed integer overflow vulnerability in ImageMagick's SIXEL decoder allows an attacker to trigger memory corruption and denial of service when processing a maliciously crafted SIXEL image file. The vulnerability occurs during buffer reallocation operations where pointer arithmetic using signed...

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

A heap Buffer Over-read vulnerability exists in the DJVU image format handler. The vulnerability occurs due to integer truncation when calculating the stride row size for pixel buffer allocation. The stride calculation overflows a 32-bit signed integer, resulting in an out-of-bounds memory reads...

CVE-2026-27691

CVE-2026-27691 affects iccDEV up to version 2.3.1.4. The root cause is a signed integer overflow in iccFromCube.cpp during multiplication, causing undefined behavior that can lead to crashes or generation of incorrect ICC profiles when processing crafted or large cube inputs. The issue has been f...

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...
