Amazon Linux AMI : openssl (ALAS-2014-427)

High Nessus Plugin ID 78485

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A memory leak flaw was found in the way OpenSSL parsed the DTLS Secure Real-time Transport Protocol (SRTP) extension data. A remote attacker could send multiple specially crafted handshake messages to exhaust all available memory of an SSL/TLS or DTLS server. (CVE-2014-3513)

A memory leak flaw was found in the way an OpenSSL handled failed session ticket integrity checks. A remote attacker could exhaust all available memory of an SSL/TLS or DTLS server by sending a large number of invalid session tickets to that server. (CVE-2014-3567)

When OpenSSL is configured with 'no-ssl3' as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be

configured to send them. (CVE-2014-3568)

Solution

Run 'yum update openssl' to update your system. Note that you may need to run 'yum clean all' first.
