Changes between 1.1.0a and 1.1.0b [xx XXX xxxx]
- *)
+ *) Fix Use After Free for large message sizes
+
+ The patch applied to address CVE-2016-6307 resulted in an issue where if a
+ message larger than approx 16k is received then the underlying buffer to
+ store the incoming message is reallocated and moved. Unfortunately a
+ dangling pointer to the old location is left which results in an attempt to
+ write to the previously freed location. This is likely to result in a
+ crash, however it could potentially lead to execution of arbitrary code.
+
+ This issue only affects OpenSSL 1.1.0a.
+
+ This issue was reported to OpenSSL by Robert Święcki.
+ (CVE-2016-6309)
+ [Matt Caswell]
