CVE-2026-965462.5 LOW

——0A one-byte out-of-bounds heap read flaw was found in GIMP's uncompressed DDS image loader. When a user opens an uncompressed DDS image, the file-dds plug-in performs an unconditional one-byte look-ahead after processing the final pixel. This may cause the plug-in to crash if the byte immediately following the pixel buffer is inaccessible; no information disclosure or code execution has been demonstrated.2h CVE-2026-965454.4 MED

——0An out-of-bounds heap read flaw was found in GIMP's TIM image loader. When a user opens a crafted 4bpp TIM image that causes promotion to an RGBA layer, the file-tim plug-in allocates an undersized row buffer but processes it using the larger RGBA row size. This can copy adjacent heap contents into the decoded image and may crash the plug-in.2h CVE-2026-888356.1 MED

——0BusyBox dpkg read_package_field() steps past a NUL terminator on malformed .deb packages, causing an out-of-bounds heap read.2h CVE-2026-79616—

——1A heap-based out-of-bounds read vulnerability exists in Foxit PDF Editor/Reader’s handling of wide strings in embedded PDF JavaScript. Insufficient validation of string-deletion ranges can cause an integer underflow, resulting in an out-of-bounds read and application crash.4h CVE-2026-918106.1 MED

——1A heap-based out-of-bounds read vulnerability exists in Foxit PDF Editor/Reader’s handling of malformed PDF image masks. Inconsistent image metadata may cause incorrect alpha-channel processing during rendering, resulting in an out-of-bounds read and application crash.4h
