Red Hat Bugzilla – Bug 142780
openssl can take thw whole cpu forever
Last modified: 2007-11-30 17:10:56 EST
Description of problem:
when using the simple script
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.
top and gnome-system-monitor shows that openssl is using 100% of cpu
an error message, a beep, anything but this :-)
openssl s_client is only for debugging purposes, please use a
different https client (curl, ...)
Otherwise, report the bug upstream.
