Hi,
The following vulnerability was published for perl.
CVE-2026-57432[0]:
| Perl versions through 5.43.10 have an integer overflow in
| S_measure_struct leading to an out-of-bounds heap read in pack and
| unpack. S_measure_struct 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.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
