Amazon Linux 2023 Security Advisory: ALAS2023-2026-3203
Advisory Released Date: 2026-10-12
Advisory Updated Date: 2026-10-12
Severity:
Medium
Issue Overview:
Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.
retrieve_hook_common reads a signed 32-bit item count from an SX_HOOK record and calls av_extend with that count plus one. A count of I32_MAX wraps the addition to a negative value.
A crafted blob passed to thaw or retrieve triggers the overflow; av_extend receives the negative count and dies with a panic, terminating the deserialization. (CVE-2026-57433)
Affected Packages:
perl-Storable
