Details
It was discovered that Kerberos did not properly determine the
acceptability of certain checksums. A remote attacker could use certain
checksums to alter the prompt message, modify a response to a Key
Distribution Center (KDC) or forge a KRB-SAFE message. (CVE-2010-1323)
It was discovered that Kerberos did not properly determine the
acceptability of certain checksums. A remote attacker could use certain
checksums to forge GSS tokens or gain privileges. This issue only affected
Ubuntu 9.10, 10.04 LTS and 10.10. (CVE-2010-1324)
It was discovered that Kerberos did not reject RC4 key-derivation
checksums. An authenticated remote user could use this issue to forge
