FreeBSD : krb5 -- client impersonation vulnerability (4ccbd40d-03f7-11e0-bf50-001a926c7637)

The MIT Kerberos team reports : MIT krb5 KDC may issue tickets not requested by a client, based on an attacker-chosen KrbFastArmoredReq. An authenticated remote attacker that controls a legitimate service principal could obtain a valid service ticket to itself containing valid KDC-generated...

FreeBSD : krb5 -- RFC 3961 key-derivation checksum handling vulnerability (1d193bba-03f6-11e0-bf50-001a926c7637)

The MIT Kerberos team reports : MIT krb5 releases incorrectly accepts RFC 3961 key-derivation checksums using RC4 keys when verifying AD-SIGNEDPATH and AD-KDC-ISSUED authorization data. An authenticated remote attacker that controls a legitimate service principal has a 1/256 chance of forging the...

FreeBSD : krb5 -- multiple checksum handling vulnerabilities (0d57c1d9-03f4-11e0-bf50-001a926c7637)

The MIT Kerberos team reports : MIT krb incorrectly accepts an unkeyed checksum with DES session keys for version 2 RFC 4121 of the GSS-API krb5 mechanism. An unauthenticated remote attacker can forge GSS tokens that are intended to be integrity-protected but unencrypted, if the targeted...

FreeBSD : krb5 -- unkeyed PAC checksum handling vulnerability (9f971cea-03f5-11e0-bf50-001a926c7637)

The MIT Kerberos team reports : MIT krb5 incorrectly accepts an unkeyed checksum for PAC signatures. An authenticated remote attacker can forge PACs if using a KDC that does not filter client-provided PAC data. This can result in privilege escalation against a service that relies on PAC contents ...

FreeBSD : krb5 -- multiple checksum handling vulnerabilities (11bbccbc-03ee-11e0-bcdb-001fc61c2a55)

The MIT Kerberos team reports : MIT krb5 clients incorrectly accept an unkeyed checksums in the SAM-2 preauthentication challenge. An unauthenticated remote attacker could alter a SAM-2 challenge, affecting the prompt text seen by the user or the kind of response sent to the KDC. Under some...
