Scientific Linux Security Update : openssl on SL6.x i386/x86_64 (20140108)
medium Nessus Plugin ID 71894
Language:
Synopsis
The remote Scientific Linux host is missing one or more security updates.Description
A flaw was found in the way OpenSSL determined which hashing algorithm to use when TLS protocol version 1.2 was enabled. This could possibly cause OpenSSL to use an incorrect hashing algorithm, leading to a crash of an application using the library. (CVE-2013-6449)It was discovered that the Datagram Transport Layer Security (DTLS) protocol implementation in OpenSSL did not properly maintain encryption and digest contexts during renegotiation. A lost or discarded renegotiation handshake packet could cause a DTLS client or server using OpenSSL to crash. (CVE-2013-6450)
A NULL pointer dereference flaw was found in the way OpenSSL handled TLS/SSL protocol handshake packets. A specially crafted handshake packet could cause a TLS/SSL client using OpenSSL to crash.
(CVE-2013-4353)
For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.
Solution
