Hi,
I accidentally entered a section header with double open square brackets in
openssl.cfg and the ca program hangs on start up with 100% CPU (e.g. type "[[
ca ]").
The culprit seems to be line 322 of crypto/conf/conf_def.c:
again:
end=eat_alpha_numeric(conf, ss);
p=eat_ws(conf, end);
if (*p != ']')
{
if (*p != '\0')
{
ss=p;
goto again;
}
CONFerr(CONF_F_DEF_LOAD_BIO,
CONF_R_MISSING_CLOSE_SQUARE_BRACKET);
goto err;
}
The character is neither alpha numeric nor whitespace, so p = ss forever.
Probably you should go for some variety of:
if (*p != '\0' && ss != p)
This will guarantee that the loop terminates.
Regards,
David L
