GnuTLS vulnerability

CVE-2014-8564 GnuTLS vulnerability
Title: GnuTLS vulnerability
Summary: GnuTLS could be made to crash or run programs if it processed a specially
crafted certificate.
Sean Burford discovered that GnuTLS incorrectly handled printing certain
elliptic curve parameters. A malicious remote server or client could use
this issue to cause GnuTLS to crash, resulting in a denial of service, or
possibly execute arbitrary code.
Instructions: In general, a standard system update will make all the necessary changes.

IssueDescription:
An out-of-bounds memory write flaw was found in the way GnuTLS parsed certain ECC (Elliptic Curve Cryptography) certificates or certificate signing requests (CSR). A malicious user could create a specially crafted ECC certificate or a certificate signing request that, when processed by an application compiled against GnuTLS (for example, certtool), could cause that application to crash or execute arbitrary code with the permissions of the user running the application.
