Package: ircd-ratbox Version: 3.0.8.dfsg-2 Severity: important Dear Maintainer,
After upgrading to 3.0.8-dfsg-2, I noticed connecting to the IRC server was very slow and resulted in hostnames not being (reverse) resolved. Upon inspection, it seemed that the ircd resolver daemon was using a lot of CPU (100% in top). A systrace did not yield anything, but an ltrace showed a continuous stream of the same line: rb_get_pseudo_random(0x7fffa62abc86, 2, 0x7f583268fba0, 0) = 1 (I'll get back to this later). I tried killing the ircd resolver daemon (had to kill it with SIGKILL) and it came back at 0% CPU usage. However, everytime a client connected, the same thing happened (cpu to 100%, ip not reverse resolved). I did a quick check in the source code and it seemed that this function was called in a tight loop if the random number that was returned is always 0xffff (a 16-bit short was requested).
