krb5 -- RFC 3961 key-derivation checksum handling vulnerability

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...

krb5 -- multiple checksum handling vulnerabilities

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...
