CVE ID :CVE-2026-57433
Published : July 13, 2026, 3:37 p.m. | 1 hour, 10 minutes ago
Description :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.
Severity: 0.0 | NA
