Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling through the parsing process of Mach-O binaries, specifically when reading size and count fields such as DataSize, DataOffset, Size, Count, and Length without proper validation. An attacker can cause excessive memory allocation, leading to memory exhaustion and process crashes by submitting a specially crafted Mach-O binary with manipulated field values.
Note: This is only exploitable if untrusted Mach-O binaries are accepted for processing, such as in CI/CD pipelines or shared signing services.
