= mbed TLS x.x.x branch released xxxx-xx-xx
+Security
+ * Fix an issue in the X.509 module which could lead to a buffer overread
+ during certificate extensions parsing. In case of receiving malformed
+ input (extensions length field equal to 0), an illegal read of one byte
+ beyond the input buffer is made. Found and analyzed by Nathan Crandall.
