Summary
Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record
Details

Storable versions before 3.41 for Perl have a signed integer overflow when deserializing a crafted SX_HOOK record.

retrievehookcommon reads a signed 32-bit item count from an SXHOOK record and calls avextend 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.
