Here are the details from the Slackware 14.0 ChangeLog:
+--------------------------+
patches/packages/openssl-1.0.1d-i486-1_slack14.0.txz: Upgraded.
 Make the decoding of SSLv3, TLS and DTLS CBC records constant time.
 This addresses the flaw in CBC record processing discovered by
 Nadhem Alfardan and Kenny Paterson. Details of this attack can be found
 at: [link moved to references]
 Thanks go to Nadhem Alfardan and Kenny Paterson of the Information
 Security Group at Royal Holloway, University of London
 (www.isg.rhul.ac.uk) for discovering this flaw and Adam Langley and
 Emilia Kasper for the initial patch.
 (CVE-2013-0169)
 [Emilia Kasper, Adam Langley, Ben Laurie, Andy Polyakov, Steve Henson]
 Fix flaw in AESNI handling of TLS 1.2 and 1.1 records for CBC mode
 ciphersuites which can be exploited in a denial of service attack.
 Thanks go to and to Adam Langley <[email protected]> for discovering
 and detecting this bug and to Wolfgang Ettlinger
 <[email protected]> for independently discovering this issue.
 (CVE-2012-2686)
 [Adam Langley]
 Return an error when checking OCSP signatures when key is NULL.
 This fixes a DoS attack. (CVE-2013-0166)
