Mandriva Linux Security Advisory MDVSA-2014:158
http://www.mandriva.com/en/support/security/
_______________________________________________________________________

Package : openssl
Date : August 8, 2014
Affected: Business Server 1.0
_______________________________________________________________________

Problem Description:

Multiple vulnerabilities has been discovered and corrected in openssl:

A flaw in OBJ_obj2txt may cause pretty printing functions such as
X509_name_oneline, X509_name_print_ex et al. to leak some information
from the stack. Applications may be affected if they echo pretty
printing output to the attacker. OpenSSL SSL/TLS clients and servers
themselves are not affected (CVE-2014-3508).

If a multithreaded client connects to a malicious server using a
resumed session and the server sends an ec point format extension it
could write up to 255 bytes to freed memory (CVE-2014-3509).

An attacker can force an error condition which causes openssl to crash
whilst processing DTLS packets due to memory being freed twice. This
can be exploited through a Denial of Service attack (CVE-2014-3505).

An attacker can force openssl to consume large amounts of memory
whilst processing DTLS handshake messages. This can be exploited
through a Denial of Service attack (CVE-2014-3506).

By sending carefully crafted DTLS packets an attacker could cause
openssl to leak memory. This can be exploited through a Denial of
Service attack (CVE-2014-3507).

OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject
to a denial of service attack. A malicious server can crash the client
with a null pointer dereference (read) by specifying an anonymous
(EC)DH ciphersuite and sending carefully crafted handshake messages
(CVE-2014-3510).

The updated packages have been upgraded to the 1.0.0n version where
these security flaws has been fixed.
