Subject: [PATCH] Add NULL checks before string compares when analyzing a cert
|
|
|
|
A user reported a segfault which was due to a broken request.
|
|
How it got broken I have no idea but it was effectively empty.
|
|
|
|
It had everything as defaults: 0, -1, UNSPECIFIED or not
|
|
present at all.
|
|
|
|
So when trying to analyze the request it did a NULL compare.
