CVE-2008-1948

The _gnutls_server_name_recv_params function in lib/ext_server_name.c in
libgnutls in gnutls-serv in GnuTLS before 2.2.4 does not properly calculate
the number of Server Names in a TLS 1.0 Client Hello message during
extension handling, which allows remote attackers to cause a denial of
service (crash) or possibly execute arbitrary code via a zero value for the
length of Server Names, which leads to a buffer overflow in session
resumption data in the pack_security_parameters function, aka
GNUTLS-SA-2008-1-1.
