An issue exists with signature validation where an attacker in a privileged network position may be able to impersonate a Kerberos KDC (Key Distribution Center), which is a service that handles authentication requests in a Kerberos network.

An out-of-bounds access issue occurs when processing a maliciously crafted media file, which may lead to unexpected app termination or corrupt process memory. This is caused by insufficient bounds checking, a process that ensures a program does not access memory outside the boundaries of a predefined buffer.

An authorization issue exists where an application with administrative privileges may be able to modify the System Keychain due to insufficient entitlement checks. Entitlement checks are security mechanisms used to verify that an app has the necessary permissions to access specific system resources.

A race condition, which occurs when the timing or order of events affects the correctness of the code, was identified. This issue could allow an application to cause unexpected system termination.
