3. Description:

 

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and

Transport Layer Security (TLS) protocols, as well as a full-strength

general-purpose cryptography library.

 

Security Fix(es):

 

* A memory leak flaw was found in the way OpenSSL handled TLS status

request extension data during session renegotiation. A remote attacker

could cause a TLS server using OpenSSL to consume an excessive amount of

memory and, possibly, exit unexpectedly after exhausting all available

memory, if it enabled OCSP stapling support. (CVE-2016-6304)

 

Red Hat would like to thank the OpenSSL project for reporting this issue.

Upstream acknowledges Shi Lei (Gear Team of Qihoo 360 Inc.) as the original

reporter.

 

4. Solution:

 

For details on how to apply this update, which includes the changes

described in this advisory, refer to:

 

https://access.redhat.com/articles/11258

 

For the update to take effect, all services linked to the OpenSSL library

must be restarted, or the system rebooted.

 

5. Bugs fixed (https://bugzilla.redhat.com/):

 

1377600 - CVE-2016-6304 openssl: OCSP Status Request extension unbounded memory growth
