Gentoo Linux Security Advisory GLSA 200803-31 - Two vulnerabilities were found in the Kerberos 4 support in KDC: A global variable is not set for some incoming message types, leading to a NULL pointer dereference or a double free() and unused portions of a buffer are not properly cleared when generating an error message, which results in stack content being contained in a reply. Versions less than 1.6.3-r1 are affected.

Ubuntu Security Notice 587-1
Posted Mar 19, 2008
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 587-1 - It was discovered that krb5 did not correctly handle certain krb4 requests. An unauthenticated remote attacker could exploit this flaw by sending a specially crafted traffic, which could expose sensitive information, cause a crash, or execute arbitrary code. A flaw was discovered in the kadmind service's handling of file descriptors. An unauthenticated remote attacker could send specially crafted requests that would cause a crash, resulting in a denial of service. Only systems with configurations allowing large numbers of open file descriptors were vulnerable.
