Kerberos RPC library code execution
| kerberos-rpc-code-execution (31422) |  High Risk |
Description:
Kerberos could allow a remote attacker to execute arbitrary code, caused by a free memory error in the RPC library of the kadmind daemon. A remote attacker could exploit this vulnerability by sending a specially-crafted Kerberos packet to execute arbitrary code on the vulnerable system or cause the application to crash.
Note: Other applications that use the RPC library may also be affected by this vulnerability.
