| CVE-2022-3116 | Hig | 0.49 | 7.5 | 0.01 | Mar 27, 2023 | The Heimdal Software Kerberos 5 implementation is vulnerable to a null pointer dereferance. An attacker with network access to an application that depends on the vulnerable code path can cause the application to crash. | ||
| CVE-2022-45142 | Hig | 0.49 | 7.5 | 0.00 | Mar 6, 2023 | The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding "!= 0" comparisons to the result of memcmp.
