Revision 05f61fb27efaf1a3f4cfa1a8d4d62c34e3c8a0fe authored by Emilia Kasper on 25 August 2014, 10:38:16 UTC, committed by Emilia Kasper on 27 August 2014, 17:42:31 UTC
The old code implicitly relies on the ASN.1 code returning a \0-prefixed buffer when the buffer length is 0. Change this to verify explicitly that the ASN.1 string has positive length.

=head1 NAME
ERR_print_errors, ERR_print_errors_fp - print error messages
=head1 SYNOPSIS
#include <openssl/err.h>
void ERR_print_errors(BIO *bp);
void ERR_print_errors_fp(FILE *fp);
=head1 DESCRIPTION
ERR_print_errors() is a convenience function that prints the error
strings for all errors that OpenSSL has recorded to B<bp>, thus
emptying the error queue.
ERR_print_errors_fp() is the same, except that the output goes to a
B<FILE>.
The error strings will have the following format:
[pid]:error:[error code]:[library name]:[function name]:[reason string]:[file name]:[line]:[optional text message]
I<error code> is an 8 digit hexadecimal number. I<library name>,
I<function name> and I<reason string> are ASCII text, as is I<optional
text message> if one was set for the respective error code.
If there is no text string registered for the given error code,
the error string will contain the numeric code.
=head1 RETURN VALUES
ERR_print_errors() and ERR_print_errors_fp() return no values.
