perl security update
Details

Perl 5 is a highly capable, feature-rich programming language with over 30 years of development. Perl 5 runs on over 100 platforms from portables to mainframes and is suitable for both rapid prototyping and large scale development projects.

Security Fix(es):

Perl versions through 5.43.10 have an integer overflow in Smeasurestruct leading to an out-of-bounds heap read in pack and unpack.

Smeasurestruct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes then guard their moves with a signed length comparison that passes when the length is negative, advancing the buffer pointer out of bounds.

A template derived from untrusted input can read heap memory past the buffer and return it to the caller.(CVE-2026-57432)

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.(CVE-2026-57433)
