Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

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.
