MIT Kerberos 5 (krb5) RPC library buffer overflow
| krb5-rpclibrary-bo (41273) |  High Risk |
Description:
The MIT Kerberos 5 (krb5) RPC library, as used by libgssrpc and kadmind, is vulnerable to a buffer overflow, caused by a memory corruption error during file descriptor handling. If a large number of open file descriptors in a process is permitted, a remote attacker could exploit this vulnerability via RPC connections to overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the kadmind service to crash.
