https://notcve.org/view.php?id=CVE-2020-13753
The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl. CLONE_NEWUSER could potentially be used to confuse xdg-desktop-portal, which allows access outside the sandbox. TIOCSTI can be used to directly execute commands outside the sandbox by writing to the controlling terminal's input buffer, similar to CVE-2017-5226. El sandbox bubblewrap de WebKitGTK y WPE WebKit, versiones anteriores a 2.28.3, no pudo bloquear apropiadamente el acceso a CLONE_NEWUSER y al ioctl TIOCSTI. CLONE_NEWUSER podría ser usada potencialmente para confundir xdg-desktop-portal, que permite el acceso fuera del sandbox. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00074.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GER2ATKZXDHM7FFYJH67ZPNZZX5VOUVM https://security.gentoo.org/glsa/202007-11 https://trac.webkit.org/changeset/262368/webkit https://usn.ubuntu.com/4422-1 https://www.debian.org/security/2020/dsa-4724 https://www.openwall.com/lists/oss-security/2020/07/10/1 • CWE-20: Improper Input Validation •
