Vulnerability from variot

The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL 0.9.8 before 0.9.8zb, 1.0.0 before 1.0.0n, and 1.0.1 before 1.0.1i allows remote DTLS servers to cause a denial of service (NULL pointer dereference and client application crash) via a crafted handshake message in conjunction with a (1) anonymous DH or (2) anonymous ECDH ciphersuite. OpenSSL is prone to a denial-of-service vulnerability. An attacker can exploit this issue to crash the affected application, denying service to legitimate users. OpenSSL prior to 0.9.8zb, 1.0.0n, and 1.0.1i are vulnerable. - The SSLv3 vulnerability known as "Padding Oracle on Downgraded Legacy Encryption" also known as "Poodle", which could be exploited remotely resulting in disclosure of information. Alternatively, you may reboot your system.

For the testing distribution (jessie), these problems will be fixed soon. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

Description:

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram Transport Layer Security (DTLS) protocols, as well as a full-strength, general purpose cryptography library.

A race condition was found in the way OpenSSL handled ServerHello messages with an included Supported EC Point Format extension. A malicious server could possibly use this flaw to cause a multi-threaded TLS/SSL client using OpenSSL to write into freed memory, causing the client to crash or execute arbitrary code. (CVE-2014-3509)

It was discovered that the OBJ_obj2txt() function could fail to properly NUL-terminate its output. This could possibly cause an application using OpenSSL functions to format fields of X.509 certificates to disclose portions of its memory. (CVE-2014-3508)

A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions. (CVE-2014-3511)

Multiple flaws were discovered in the way OpenSSL handled DTLS packets. A remote attacker could use these flaws to cause a DTLS server or client using OpenSSL to crash or use excessive amounts of memory. (CVE-2014-3510)

All OpenSSL users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all services linked to the OpenSSL library (such as httpd and other SSL-enabled services) must be restarted or the system rebooted.

Solution:

Before applying this update, make sure all previously released errata relevant to your system have been applied.
