A vulnerability in MIT Kerberos 5 could lead to a Denial of Service condition.
|Package||app-crypt/mit-krb5 on all architectures|
|Affected versions||< 1.18.2-r2|
|Unaffected versions||>= 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"
