Default Stack Clash

Quote:
The Stack Clash is a vulnerability in the memory management of several operating systems. It affects Linux, OpenBSD, NetBSD, FreeBSD and Solaris, on i386 and amd64. It can be exploited by attackers to corrupt memory and execute arbitrary code.

Thanks,
I see they show this :
OpenBSD
https://ftp.openbsd.org/pub/OpenBSD/...subr.patch.sig

But what I wonder is what need to be done to install it ?
And has any body installed it ?

See the syspatch(8) man page.

Edited to add, yes, I have this patch on 5 systems, in 2 architectures.

It's best to keep an eye on the errata page from time to time...

https://www.openbsd.org/errata61.html

So if you haven't applied those patches, or if you're not running OpenBSD -stable, then it's probably time.

The manual seems clear enough on this , how ever I am wondering
if this is correct for my "installurl" file:
Code:
https://ftp.openbsd.org/pub/OpenBSD/patches/6.1/common/
When I do this, it comes up blank,..
Code:
# syspatch -c
#
also with the -l option.
When I run 'syspatch' it pauses a little while, then
the prompt, no errors, but no success message either ,..
Code:
# syspatch
#
Is that to be expected ?
Thanks

I will guess that your installation or upgrade was entirely from local media, and that as a result you do not have an installurl(5) file.

See the FILES section and the SEE ALSO section of the syspatch(8) man page.

Actually I do have the 'installurl', I use it to install packages,
I see what I was missing now,
Quote:
The /etc/installurl file contains a single line specifying an OpenBSD
mirror server URL, such as
Duh, I had added the other url, thinking I needed to do that, so I had 2 lines,..
I removed it ,(the extra line) and just kept the same url I use for packages, and it is installing patches now,
thanks,..

New 4.4.74 kernel packages for Slackware 14.2 and -current have fixes related to the Stack Clash problem.
