CVE-2026-57432

*** Pendiente de traducción *** 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.<br /> <br /> S_measure_struct adds each item&amp;#39;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.<br /> <br /> A template derived from untrusted input can read heap memory past the buffer and return it to the caller.
