[code]sudo fallocate -l 8G /swapfile[/code]
Why 8 gigabytes when I have ample RAM and an SSD? Because I never, ever want to worry about it again. I want to be able to open up every app I have and leave them open for a month. You do you and decide how big you want it to be!
[code]sudo chmod 600 /swapfile[/code]
[code]sudo mkswap /swapfile[/code]
And turn it on with:
[code]sudo swapon /swapfile[/code]
[code]sudo nano /etc/fstab[/code]
And add this at the bottom of that document:
[code]/swapfile none swap sw 0 0[/code]
USN-4467-1 fixed vulnerabilities in QEMU. The fix for CVE-2020-13754
introduced a regression in certain environments. This update fixes the
problem.
We apologize for the inconvenience.
Original advisory details:
Ren Ding, Hanqing Zhao, Alexander Bulekov, and Anatoly Trosinenko
discovered that the QEMU incorrectly handled certain msi-x mmio operations.
An attacker inside a guest could possibly use this issue to cause QEMU to
crash, resulting in a denial of service. (CVE-2020-13754)
Pasi Saarinen discovered that OpenLDAP incorrectly handled certain short
timestamps. A remote attacker could possibly use this issue to cause
OpenLDAP to crash, resulting in a denial of service.
It was discovered that the GDK-PixBuf library did not properly handle
certain GIF images. If an user or automated system were tricked into
opening a specially crafted GIF file, a remote attacker could use this flaw
to cause GDK-PixBuf to crash, resulting in a denial of service.
