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.
It was discovered that the Datagram Transport Layer Security (DTLS)
protocol implementation in OpenSSL leaked timing information when
performing certain operations. A remote attacker could possibly use
this flaw to retrieve plain text from the encrypted packets by using a
DTLS server as a padding oracle. (CVE-2011-4108)
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
A denial of service flaw was found in the RFC 3779 implementation in
OpenSSL. A remote attacker could use this flaw to make an application
using OpenSSL exit unexpectedly by providing a specially crafted X.509
certificate that has malformed RFC 3779 extension data.
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. (CVE-2011-4619)
All OpenSSL users should upgrade to these updated packages, which
contain backported patches to resolve these issues. For the update to
take effect, all services linked to the OpenSSL library must be
restarted, or the system rebooted.
