openssl can take thw whole cpu forever
Last modified: 2007-11-30 17:10:56 EST
Description of problem: when using the simple script #!/bin/sh echo "GET /update.asp?u=$1&p=$2&cmd=update&set=2&offline=0" | openssl s_client -quiet -connect www.changeip.com:443 & to update a dynamic dns, sometimes something wrong can happen (ie network timeout, connection down, etc). When this happens, openssl gets stucked, using 100% of cpu resources, forever. You have to kill it to use the computer again. Version-Release number of selected component : openssl-0.9.7a-40.src.rpm How reproducible: Sometimes Steps to Reproduce: 1. run this script 2. something wrong (which of course I don't know what is) happens 3. openssl keeps up consuming cpu power. Actual results: top and gnome-system-monitor shows that openssl is using 100% of cpu Expected results: an error message, a beep, anything but this :-) Additional info:
openssl s_client is only for debugging purposes, please use a different https client (curl, ...) Otherwise, report the bug upstream.
