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...

coreutils: GNU coreutils uniq: Denial of Service and information disclosure via out-of-bounds read with multibyte input

A flaw was found in GNU coreutils uniq. When processing specially crafted multibyte input with the --check-chars option, an attacker can trigger an out-of-bounds read. This vulnerability can lead to a denial of service DoS due to an application crash and potentially expose sensitive information...
