Vulnerability in Gnu Transport Layer Security (GnuTLS) affects IBM SmartCloud Provisioning 2.1 for IBM Provided Software Virtual Appliance (CVE-2014-3466).
CVE ID: CVE-2014-3466
DESCRIPTION: The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS). A flaw was found in the way GnuTLS parsed session IDs from ServerHello messages of the TLS/SSL handshake. malicious server might use this flaw to send an excessively long session ID value, which would trigger a buffer overflow in a connecting TLS/SSL client application using GnuTLS. This action then causes the client application to crash or, possibly, execute arbitrary code.
