Synopsis :

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

Description :

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.

Solution :

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'

Risk factor :

High / CVSS Base Score : 9.3
(CVSS2#AV:N/AC:M/Au:N/C:C/I:C/A:C)
