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