perl: Perl: Information disclosure via integer overflow in pack/unpack operations

A flaw was found in Perl. An integer overflow vulnerability in the Smeasurestruct function, specifically when handling pack and unpack templates with large repeat counts, can lead to an out-of-bounds heap read. This allows an attacker, by providing a specially crafted template, to read sensitive...
