Description Arvid Requate

2015-06-11 21:24:33 CEST

New issues have been discovered in openssl:

* Invalid free in DTLS (CVE-2014-8176)
* Malformed ECParameters causes infinite loop (CVE-2015-1788)
* Exploitable out-of-bounds read in X509_cmp_time (CVE-2015-1789)
* PKCS7 crash with missing EnvelopedContent (CVE-2015-1790)
* race condition in NewSessionTicket (CVE-2015-1791)
* CMS verify infinite loop with unknown hash function (CVE-2015-1792)

* The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. (CVE-2015-4000)
