CVE-2008-1949

CVE-2008-1949 affects the GnuTLS stack (libgnutls in gnutls-serv). The flaw is in _gnutls_recv_client_kx_message, which can erroneously continue processing Client Hello messages within a TLS record after one has been handled, causing a NULL dereference and a crash (denial of service). Affected co...

CVE-2008-1949

The gnutlsrecvclientkxmessage function in lib/gnutlskx.c in libgnutls in gnutls-serv in GnuTLS before 2.2.4 continues to process Client Hello messages within a TLS message after one has already been processed, which allows remote attackers to cause a denial of service NULL dereference and crash v...

CVE-2008-1948

CVE-2008-1948 affects GnuTLS before 2.2.4. The _gnutls_server_name_recv_params function in libext_server_name.c within libgnutls/gnutls-serv mishandles the Server Names count in TLS 1.0 Client Hello extensions, causing a buffer overflow in session resumption data and potentially a crash or arbitr...

CVE-2008-1950

CVE-2008-1950 affects the GnuTLS stack (libgnutls) with an integer signedness flaw in _gnutls_ciphertext2compressed, exploitable via a crafted Random field in an encrypted Client Hello within a TLS record with invalid Record Length. This can trigger a buffer over-read and cause a denial of servic...

GnuTLS: Execution of arbitrary code

Background GnuTLS is an implementation of Secure Sockets Layer SSL 3.0 and Transport Layer Security TLS 1.0, 1.1 and 1.2. Description Ossi Herrala and Jukka Taimisto of Codenomicon reported three vulnerabilities in libgnutls of GnuTLS: "Client Hello" messages containing an invalid server name can...

GNUTLS-SA-2008-1-1 GnuTLS buffer overflow

The gnutlsservernamerecvparams function in lib/extservername.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...
