2019-11-04Don't assume the type we read was the type we expectedMatt Caswell
i2v_GENERAL_NAME and GENERAL_NAME_print were assuming that the type of of a GENERAL_NAME (OTHERNAME) that we read in was the type we expected it to be. If its something else then this can cause unexpected behaviour. In the added fuzz test case an OOB read was occurring. This issue was recently added by commit 4baee2d. Credit to OSSFuzz for finding this issue.

2017-03-12Fix out-of-memory condition in confMatt Caswell
conf has the ability to expand variables in config files. Repeatedly doing this can lead to an exponential increase in the amount of memory required. This places a limit on the length of a value that can result from an expansion. Credit to OSS-Fuzz for finding this problem.
