GLSA-200707-11 : MIT Kerberos 5: Arbitrary remote code execution

High Nessus Plugin ID 25793


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200707-11 (MIT Kerberos 5: Arbitrary remote code execution)

kadmind is affected by multiple vulnerabilities in the RPC library shipped with MIT Kerberos 5. It fails to properly handle zero-length RPC credentials (CVE-2007-2442) and the RPC library can write past the end of the stack buffer (CVE-2007-2443). Furthermore kadmind fails to do proper bounds checking (CVE-2007-2798).
Impact :

A remote unauthenticated attacker could exploit these vulnerabilities to execute arbitrary code with root privileges.
Workaround :

There is no known workaround at this time.


All MIT Kerberos 5 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-crypt/mit-krb5-1.5.2-r3'
