The "mechglue" abstraction interface of the GSS-API library for Kerberos 5 1.5 through 1.5.1, as used in Kerberos administration daemon (kadmind) and other products that use this library, allows remote attackers to cause a denial of service (crash) via unspecified vectors that cause mechglue to free uninitialized pointers.

Bugs in the handling of pointers to uninitializes resp. already freed memory could potentially be abused by attackers to execute code.
(CVE-2006-6144 / CVE-2006-6143)

Bugs in the handling of pointers to uninitializes resp. already freed memory could potentially be abused by attackers to execute code (CVE-2006-6144, CVE-2006-6143).

The remote host is affected by the vulnerability described in GLSA-200701-21 (MIT Kerberos 5: Arbitrary Remote Code Execution)

    The Kerberos administration daemon, and possibly other applications     using the GSS-API or RPC libraries, could potentially call a function     pointer in a freed heap buffer, or attempt to free an uninitialized     pointer.
  Impact :

    A remote attacker may be able to crash an affected application, or     potentially execute arbitrary code with root privileges.
  Workaround :

    There is no known workaround at this time.

This update incorporates fixes for recently-announced bugs found in the kadmind daemon.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
