coreutils: GNU coreutils unexpand: Denial of Service via crafted tab stop values

A flaw was found in GNU coreutils, specifically in the unexpand utility. This vulnerability, a heap-based buffer overflow, occurs due to an integer overflow when unexpand processes unusually large tab stop values provided by a local attacker. This can lead to an undersized memory buffer, allowing...
