Incorrect cross-realm trust handling in Heimdal

Heimdal does not correctly validate the transited' field of Kerberos tickets when computing the authentication path. This could allow a rogue KDC with which cross-realm relationships have been established to impersonate any KDC in the authentication path...

CVE-2003-0082

The CVE-2003-0082 issue affects the KDC in Kerberos 5 (krb5) 1.2.7 and earlier. A remote, authenticated attacker can trigger a protocol request that causes the KDC to corrupt its heap (buffer underrun), leading to a denial of service (KDC crash) within the same realm. The connected advisories con...

CVE-2003-0060

CVE-2003-0060 describes a format-string vulnerability in the MIT Kerberos V5 KDC logging routines prior to version 1.2.5. The issue allows remote attackers to trigger a denial of service (crash) and, potentially, to execute arbitrary code via format string specifiers in Kerberos principal names. ...

MIT Kerberos V5 KDC logging routines use unsafe format strings

Overview Early releases of the MIT Kerberos V5 KDC contain format string vulnerabilities that can be used by unauthenticated remote attackers to conduct denial of service attacks on KDC servers. Description Logging routines in some unspecified versions of the MIT Kerberos V5 Key Distribution Cent...
