MIT Kerberos 5: Denial of service

MIT Kerberos 5: Denial of service A vulnerability in MIT Kerberos 5 could lead to a Denial of Service condition. mit-krb5 2020-11-16 2020-11-16 753281 remote 1.18.2-r2 1.18.2-r2

The MIT Kerberos 5 implementation provides a command line telnet client which is used for remote login via the telnet protocol.

It was discovered that MIT Kerberos network authentication system, krb5, did not properly handle ASN.1-encoded Kerberos messages.

A remote attacker could send a specially crafted Kerberos message, possibly resulting in a Denial of Service condition.

There is no known workaround at this time.

All MIT Kerberos 5 users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.18.2-r2"
