PolarSSL 1.1.6 released

Description

This release contains backported patches from the PolarSSL 1.2 branch to the PolarSSL 1.1 branch!

Security related

The main reason of this release is the reduction of a possible timing side channel in the PolarSSL SSL module during decryption of the buffer due to badly formatted padding in the incoming message. Check out PolarSSL Security Advisory 2013-01 for more information. To help some flags have been added to manipulate behaviour of the SSL module with regards to debugging of bad padding bytes.

In addition, a possible timing difference due to bad padding in PKCS#1 v1.5 operations has been reduced.

Fixes:

  • CVE-2013-0169 - TLS and DTLS protocol issue (Lucky Thirteen)
  • CVE-2013-1621 - Out-of-bounds comparisons

Changes

A dummy error_strerror() function has been added that makes it easier to use the function in code without needing constant checks to see if POLARSSL_ERROR_C is defined.

Bug fixes

Some minor bug fixes and typo fixes are included as well.

Who should update

Our advice for users of the PolarSSL 1.1 branch is to update:

Our advice for users of the PolarSSL 1.2 branch is to update to the released PolarSSL 1.2.6 instead!
