MIT Kerberos administration daemon (kadmind) gssrpc__svcauth_gssapi() function code execution

kerberos-gssrpcsvcauthgssapi-code-execution (35082)

High Risk

Description:

The MIT Kerberos administration daemon (kadmind) could allow a remote attacker to execute arbitrary code on the system, caused by an uninitialized pointer free vulnerability in the gssrpc__svcauth_gssapi() function. By sending a specially-crafted RPC request, a remote attacker could corrupt memory and execute arbitrary code on the system or cause the daemon to crash.
