OpenSSL CHANGES
_______________
+ Changes between 1.0.1m and 1.0.1n [11 Jun 2015]
+
+ *) Malformed ECParameters causes infinite loop
+
+ When processing an ECParameters structure OpenSSL enters an infinite loop
+ if the curve specified is over a specially malformed binary polynomial
+ field.
+
+ This can be used to perform denial of service against any
+ system which processes public keys, certificate requests or
+ certificates. This includes TLS clients and TLS servers with
+ client authentication enabled.
+
+ This issue was reported to OpenSSL by Joseph Barr-Pixton.
+ (CVE-2015-1788)
+ [Andy Polyakov]
+
+ *) Exploitable out-of-bounds read in X509_cmp_time
+
+ X509_cmp_time does not properly check the length of the ASN1_TIME
+ string and can read a few bytes out of bounds. In addition,
+ X509_cmp_time accepts an arbitrary number of fractional seconds in the
+ time string.
+
+ An attacker can use this to craft malformed certificates and CRLs of
+ various sizes and potentially cause a segmentation fault, resulting in
+ a DoS on applications that verify certificates or CRLs. TLS clients
+ that verify CRLs are affected. TLS clients and servers with client
+ authentication enabled may be affected if they use custom verification
+ callbacks.
+
+ This issue was reported to OpenSSL by Robert Swiecki (Google), and
+ independently by Hanno Böck.
+ (CVE-2015-1789)
+ [Emilia Käsper]
+
+ *) PKCS7 crash with missing EnvelopedContent
+
+ The PKCS#7 parsing code does not handle missing inner EncryptedContent
+ correctly. An attacker can craft malformed ASN.1-encoded PKCS#7 blobs
+ with missing content and trigger a NULL pointer dereference on parsing.
+
+ Applications that decrypt PKCS#7 data or otherwise parse PKCS#7
+ structures from untrusted sources are affected. OpenSSL clients and
+ servers are not affected.
+
+ This issue was reported to OpenSSL by Michal Zalewski (Google).
+ (CVE-2015-1790)
+ [Emilia Käsper]
+
+ *) CMS verify infinite loop with unknown hash function
+
+ When verifying a signedData message the CMS code can enter an infinite loop
+ if presented with an unknown hash function OID. This can be used to perform
+ denial of service against any system which verifies signedData messages using
+ the CMS code.
+ This issue was reported to OpenSSL by Johannes Bauer.
+ (CVE-2015-1792)
+ [Stephen Henson]
+
+ *) Race condition handling NewSessionTicket
+
+ If a NewSessionTicket is received by a multi-threaded client when attempting to
+ reuse a previous ticket then a race condition can occur potentially leading to
+ a double free of the ticket data.
+ (CVE-2015-1791)
+ [Matt Caswell]
+
+ *) Reject DH handshakes with parameters shorter than 768 bits.
+ [Kurt Roeckx and Emilia Kasper]
+
Changes between 1.0.1l and 1.0.1m [19 Mar 2015]
*) Segmentation fault in ASN1_TYPE_cmp fix
