The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200805-20
(GnuTLS: Execution of arbitrary code)
Ossi Herrala and Jukka Taimisto of Codenomicon reported three
vulnerabilities in libgnutls of GnuTLS:
'Client Hello' messages containing an invalid server name can lead to a
buffer overflow when evaluating 'Security Parameters' (CVE-2008-1948).
Multiple 'Client Hello' messages can lead to a NULL pointer dereference
A TLS handshake including an encrypted 'Client Hello' message and an
invalid record length could lead to a buffer overread (CVE-2008-1950).
Unauthenticated remote attackers could exploit these vulnerabilities to
cause Denial of Service conditions in daemons using GnuTLS. The first
vulnerability (CVE-2008-1948) might allow for the execution of
arbitrary code with the privileges of the daemon handling incoming TLS
There is no known workaround at this time.
