ImageMagick has heap-buffer-overflow via signed integer overflow in WriteUHDRImage when writing UHDR images with large dimensions

WriteUHDRImage in coders/uhdr.c uses int arithmetic to compute the pixel buffer size. When image dimensions are large, the multiplication overflows 32-bit int, causing an undersized heap allocation followed by an out-of-bounds write. This can crash the process or potentially lead to an out of...

CVE-2026-25970 ImageMagick SIXEL Decoder Has Signed Integer Overflow, Leading to Memory Corruption

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 signed integer overflow vulnerability in ImageMagick's SIXEL decoder allows an attacker to trigger memory corruption and denial of service when processing a...

CVE-2026-25794

ImageMagick (WriteUHDRImage in coders/uhdr.c) is affected by a signed 32-bit int overflow when computing the pixel buffer size for large dimensions, causing an undersized heap allocation and an out-of-bounds write. A patch is available in version 7.1.2-15 that fixes this issue. The CVE entry note...

CVE-2026-25794 ImageMagick has heap-buffer-overflow via signed integer overflow in `WriteUHDRImage` when writing UHDR images with large dimensions

ImageMagick is free and open-source software used for editing and manipulating digital images. WriteUHDRImage in coders/uhdr.c uses int arithmetic to compute the pixel buffer size. Prior to version 7.1.2-15, when image dimensions are large, the multiplication overflows 32-bit int, causing an...

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...

libsoup: Signed to Unsigned Conversion Error Leading to Stack-Based Buffer Overflow in libsoup NTLM Authentication

A flaw was identified in the NTLM authentication handling of the libsoup HTTP library, used by GNOME and other applications for network communication. When processing extremely long passwords, an internal size calculation can overflow due to improper use of signed integers. This results in...
