Descripción
*** 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&#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.
