Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound through the processing of a 32-bit attribute count received from a remote server in the publickey subsystem. An attacker can cause a heap buffer overflow by sending a specially crafted response that triggers an integer overflow during memory allocation, leading to memory corruption and potential execution of arbitrary code.
