Description Henrik Nordstrom 2003-02-08 00:36:59 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.2.19-6.2.1 i586)

Description of problem:
Contrary to the documentation EVP_DecryptInit coredumps if the EVP context is
not initialized.


The OpenSSL team reports that this bug was fixed a couple of weeks ago.

Also received the following oneliner which from another user:

Subject: Re: [ #494] 0.9.7 EVP_DecryptInit coredumps if ctx not

I haven't checked, but this may already be fixed in the latest source.  In any
case, there's a one-line fix (I ran into the same problem): change
EVP_DecryptInit() so that it calls EVP_CipherInit() rather than

And the OpenSSL team response to this fix was:

Agreed, fix being checked in. Thanks for the report.
