Does this matter?
Lower severity and a low EPSS score (0.12%). Track it; it rarely justifies an emergency change on its own.
Description
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.
