Major changes in 1.20.1 (2022-11-15)

  • Fix integer overflows in PAC parsing [CVE-2022-42898].
  • Fix null deref in KDC when decoding invalid NDR.
  • Fix memory leak in OTP kdcpreauth module.
  • Fix PKCS11 module path search.

The CVE is where Kerberos libraries and AD DC failed to guard against integer overflows when parsing a PAC on a 32-bit system, which allowed an attacker with a forged PAC to corrupt the heap.

It does not seem to affect 64-bit systems.
