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"
OS | Version | Architecture | Package | Version | Filename |
---|---|---|---|---|---|
Gentoo | any | all | app-crypt/mit-krb5 | < 1.18.2-r2 | UNKNOWN |
