CVE-2026-9538 Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header

Archive::Tar versions before 3.10 for Perl allow memory exhaustion via attacker controlled entry size field in tar header. readtar 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...

CVE-2026-9538

CVE-2026-9538 affects Archive::Tar prior to 3.10 for Perl. A crafted tar header can set a multi‑gigabyte size, causing _read_tar() to allocate a scalar of that size, leading to memory exhaustion. The vulnerability arises from reading entry payloads with a size block derived from the header withou...
