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.
