OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3)
and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.
Multiple numeric conversion errors, leading to a buffer overflow, were
found in the way OpenSSL parsed ASN.1 (Abstract Syntax Notation One) data
from BIO (OpenSSL’s I/O abstraction) inputs. Specially-crafted DER
(Distinguished Encoding Rules) encoded data read from a file or other BIO
input could cause an application using the OpenSSL library to crash or,
potentially, execute arbitrary code. (CVE-2012-2110)
A double free flaw was discovered in the policy checking code in OpenSSL.
A remote attacker could use this flaw to crash an application that uses
OpenSSL by providing an X.509 certificate that has specially-crafted
policy extension data. (CVE-2011-4109)
An information leak flaw was found in the SSL 3.0 protocol implementation
in OpenSSL. Incorrect initialization of SSL record padding bytes could
cause an SSL client or server to send a limited amount of possibly
sensitive data to its SSL peer via the encrypted connection.
It was discovered that OpenSSL did not limit the number of TLS/SSL
handshake restarts required to support Server Gated Cryptography. A remote
attacker could use this flaw to make a TLS/SSL server using OpenSSL consume
an excessive amount of CPU by continuously restarting the handshake.
This update also fixes additional security issues in OpenSSL that are not
exposed in JBoss Enterprise Web Server: CVE-2011-4108, CVE-2012-0884,
CVE-2012-1165, and CVE-2012-2333.
