krb5 -- ASN.1 decoder denial-of-service vulnerability
An advisory published by the MIT Kerberos team says: The ASN.1 decoder library in the MIT Kerberos 5 distribution is vulnerable to a denial-of-service attack causing an infinite loop in the decoder. The KDC is vulnerable to this attack. An unauthenticated remote attacker can cause a KDC or...
krb5 -- double-free vulnerabilities
An advisory published by the MIT Kerberos team says: The MIT Kerberos 5 implementation's Key Distribution Center KDC program contains a double-free vulnerability that potentially allows a remote attacker to execute arbitrary code. Compromise of a KDC host compromises the security of the entire...
Mandrake Linux Security Advisory : krb5 (MDKSA-2003:043-1)
Multiple vulnerabilities have been found in the Kerberos network authentication system. The MIT Kerberos team have released an advisory detailing these vulnerabilities, a description of which follows. An integer signedness error in the ASN.1 decoder before version 1.2.5 allows remote attackers to...
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-2003-0072
CVE-2003-0072 describes a remote, authenticated denial-of-service in the Kerberos 5 Key Distribution Center (KDC) for krb5 1.2.7 and earlier. A specific protocol request can trigger an out-of-bounds read of an array, crashing KDCs within the same realm. Connected advisories reference this CVE amo...
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...

DEBIAN-CVE-2003-0058
MIT Kerberos V5 Key Distribution Center KDC before 1.2.5 allows remote authenticated attackers to cause a denial of service crash on KDCs within the same realm via a certain protocol request that causes a null dereference...
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. ...
CVE-2003-0060
Format string vulnerabilities in the logging routines for MIT Kerberos V5 Key Distribution Center KDC before 1.2.5 allow remote attackers to cause a denial of service crash and possibly execute arbitrary code via format string specifiers in Kerberos principal names...
CVE-2003-0060: Undefined Security Weakness
Format string vulnerabilities in the logging routines for MIT Kerberos V5 Key Distribution Center KDC before 1.2.5 allow remote attackers to cause a denial of service crash and possibly 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...
