CVE-2025-15614
Estado: AplazadaMedia (4.8)—
ugrep before 7.6.0 contains a heap buffer over-read vulnerability in the LZW decompressor when processing crafted .Z archive files. Attackers can supply malformed .Z files that cause the decompressor to read one byte past the allocated heap buffer, potentially crashing the process.
