Arch Linux Security Advisory ASA-201905-3
Date : 2019-05-06
CVE-ID : CVE-2019-11461
Package : nautilus
Type : sandbox escape
Remote : No
Link : https://security.archlinux.org/AVG-956
The package nautilus before version 3.32.1-1 is vulnerable to sandbox
Upgrade to 3.32.1-1.
# pacman -Syu "nautilus>=3.32.1-1"
The problem has been fixed upstream in version 3.32.1.
An issue was discovered in GNOME Nautilus 3.30 prior to 3.30.6 and 3.32
prior to 3.32.1. A compromised thumbnailer may escape the bubblewrap
sandbox used to confine thumbnailers by using the TIOCSTI ioctl to push
characters into the input buffer of the thumbnailer's controlling
terminal, allowing an attacker to escape the sandbox if the thumbnailer
has a controlling terminal. This is due to improper filtering of the
TIOCSTI ioctl on 64-bit systems, similar to CVE-2019-10063.
A local attacker is able to escape the sandbox.
