UBUNTU-CVE-2026-66757

A flaw was found in the file-sgi plugin in GIMP. When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions ysize and zsize are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value 65535, the...

CVE-2026-15003 Binutils: gnu binutils: heap-buffer-overflow in linker leads to information disclosure and denial of service

A flaw was found in the GNU Binutils Binary Utilities linker. This vulnerability, a heap-buffer-overflow read CWE-125, occurs when the linker processes a specially crafted 32-bit XCOFF Extended Common Object File Format object file. An attacker could exploit this by providing a malicious file,...

CVE-2026-15003

CVE-2026-15003 affects the GNU Binutils linker. A heap-buffer-overflow read (CWE-125) occurs when processing a crafted 32-bit XCOFF object file, enabling an out-of-bounds memory read. This may cause information disclosure of heap data and a Denial of Service through linker crash. No specific vers...
