The following vulnerability was published[0] for Archive-Tar (bundled with perl): CVE ID: CVE-2026-9538 Distribution: Archive-Tar Versions: before 3.10 MetaCPAN: https://metacpan.org/dist/Archive-Tar VCS Repo: https://github.com/jib/archive-tar-new Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header Description ----------- Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. _read_tar() reads each entry's payload with $handle->read($$data, $block), where $block is derived from the entry's 12-byte size field in the tar header with no upper bound on that value. A crafted header declaring a multi-gigabyte size causes Perl to allocate a scalar of that size. [0] https://lists.security.metacpan.org/cve-announce/msg/40396448/ -- Niko Tyni [email protected]
