CVE-2026-77219

GNU Emacs before 31.0.91 is affected by an integer overflow in the PBM/PPM/PGM image loader . The loader multiplies image dimensions and channel count using signed integer arithmetic; for sufficiently large values the result wraps to a negative number, bypassing the bounds check and causing the p...

CVE-2026-56289

A flaw was found in GNU patch. This vulnerability allows a remote attacker to cause a Denial of Service DoS by supplying a specially crafted patch file. The improper validation of hunk single block of changes in diff line offsets in unified-diff input can lead to an effectively infinite processin...

CVE-2026-56288

A flaw was found in GNU patch. An attacker can exploit this by providing a specially crafted patch file, which leads to a NULL pointer dereference. This improper handling of end-of-file markers can corrupt internal data structures, causing the utility to crash. This results in a denial of service...
