CVE-2011-4128

Status Candidate

Overview

Buffer overflow in the gnutls_session_get_data function in lib/gnutls_session.c in GnuTLS 2.12.x before 2.12.14 and 3.x before 3.0.7, when used on a client that performs nonstandard session resumption, allows remote TLS servers to cause a denial of service (application crash) via a large SessionTicket.

Ubuntu Security Notice USN-1418-1
Posted Apr 6, 2012
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1418-1 - Alban Crequy discovered that the GnuTLS library incorrectly checked array bounds when copying TLS session data. A remote attacker could crash a client application, leading to a denial of service, as the client application prepared for TLS session resumption. Matthew Hall discovered that the GnuTLS library incorrectly handled TLS records. A remote attacker could crash client and server applications, leading to a denial of service, by sending a crafted TLS record. Various other issues were also addressed.

Red Hat Security Advisory 2012-0429-01
Posted Mar 28, 2012
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2012-0429-01 - The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security. A flaw was found in the way GnuTLS decrypted malformed TLS records. This could cause a TLS/SSL client or server to crash when processing a specially-crafted TLS record from a remote TLS/SSL connection peer. A boundary error was found in the gnutls_session_get_data() function. A malicious TLS/SSL server could use this flaw to crash a TLS/SSL client or, possibly, execute arbitrary code as the client, if the client passed a fixed-sized buffer to gnutls_session_get_data() before checking the real size of the session data provided by the server.

Red Hat Security Advisory 2012-0428-01 - The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security. GnuTLS includes libtasn1, a library developed for ASN.1 structures management that includes DER encoding and decoding. A flaw was found in the way GnuTLS decrypted malformed TLS records. This could cause a TLS/SSL client or server to crash when processing a specially-crafted TLS record from a remote TLS/SSL connection peer.
