Arch Linux Security Advisory ASA-201905-3 ========================================= Severity: High Date : 2019-05-06 CVE-ID : CVE-2019-11461 Package : nautilus Type : sandbox escape Remote : No Link : https://security.archlinux.org/AVG-956 Summary ======= The package nautilus before version 3.32.1-1 is vulnerable to sandbox escape. Resolution ========== Upgrade to 3.32.1-1. # pacman -Syu "nautilus>=3.32.1-1" The problem has been fixed upstream in version 3.32.1. Workaround ========== None. Description =========== 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. Impact ====== A local attacker is able to escape the sandbox.
