Name of the Vulnerable Software and Affected Versions Little Snitch versions 3.0 through 3.6.1

Description The issue is related to a buffer overflow that could be locally exploited, potentially leading to an escalation of privileges and unauthorized access to the operating system. This buffer overflow is due to insufficient checking of parameters to the OSMalloc and copyin kernel API calls.
