Mandriva Linux Security Advisory 2014-105 - The dtls1_get_message_fragment function in d1_both.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote attackers to cause a denial of service via a DTLS hello message in an invalid DTLS handshake. OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the CCS Injection vulnerability. The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when an anonymous ECDH cipher suite is used, allows remote attackers to cause a denial of service by triggering a NULL certificate value. The updated packages have been patched to correct these issues.

Mandriva Linux Security Advisory MDVSA-2014:105

_______________________________________________________________________
Package : openssl
Date : June 9, 2014
Affected: Enterprise Server 5.0
_______________________________________________________________________
Problem Description:
Multiple vulnerabilities has been discovered and corrected in openssl:
The dtls1_get_message_fragment function in d1_both.c in OpenSSL before
0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h allows remote
attackers to cause a denial of service (recursion and client crash)
via a DTLS hello message in an invalid DTLS handshake (CVE-2014-0221).
OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before
1.0.1h does not properly restrict processing of ChangeCipherSpec
messages, which allows man-in-the-middle attackers to trigger use of a
zero-length master key in certain OpenSSL-to-OpenSSL communications,
and consequently hijack sessions or obtain sensitive information,
via a crafted TLS handshake, aka the CCS Injection vulnerability
(CVE-2014-0224).
The ssl3_send_client_key_exchange function in s3_clnt.c in OpenSSL
before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h, when
an anonymous ECDH cipher suite is used, allows remote attackers to
cause a denial of service (NULL pointer dereference and client crash)
by triggering a NULL certificate value (CVE-2014-3470).
The updated packages have been patched to correct these issues.
