Mandriva Linux Security Advisory : openssl (MDVSA-2014:203)

Synopsis :

The remote Mandriva Linux host is missing one or more security

Description :

Multiple vulnerabilities has been discovered and corrected in
openssl :

OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications
to block the ability for a MITM attacker to force a protocol
downgrade. Some client applications (such as browsers) will reconnect
using a downgraded protocol to work around interoperability bugs in
older servers. This could be exploited by an active man-in-the-middle
to downgrade connections to SSL 3.0 even if both sides of the
connection support higher protocols. SSL 3.0 contains a number of
weaknesses including POODLE (CVE-2014-3566).

When an OpenSSL SSL/TLS/DTLS server receives a session ticket the
integrity of that ticket is first verified. In the event of a session
ticket integrity check failing, OpenSSL will fail to free memory
causing a memory leak. By sending a large number of invalid session
tickets an attacker could exploit this issue in a Denial Of Service
attack (CVE-2014-3567).

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