BubblewrapLauncher.cpp in WebKitGTK and WPE WebKit before 2.34.1 allows a limited sandbox bypass that allows a sandboxed process to trick host processes into thinking the sandboxed process is not confined by the sandbox, by abusing VFS syscalls that manipulate its filesystem namespace. The impact is limited to host services that create UNIX sockets that WebKit mounts inside its sandbox, and the sandboxed process remains otherwise confined. ... El archivo BubblewrapLauncher.cpp en WebKitGTK y WPE WebKit versiones anteriores a 2.34.1, permite una omisión limitada del sandbox que permite a un proceso con sandbox engañar a procesos anfitriones para que piensen que el proceso con sandbox no está confinado por la sandbox, al abusar de las llamadas al sistema VFS que manipulan su espacio de nombres del sistema de archivos. El impacto se limita a servicios de host que crean sockets UNIX que WebKit monta dentro de su sandbox, y el proceso con sandbox permanece confinado de otra manera. • http://www.openwall.com/lists/oss-security/2021/10/26/9 http://www.openwall.com/lists/oss-security/2021/10/27/1 http://www.openwall.com/lists/oss-security/2021/10/27/2 http://www.openwall.com/lists/oss-security/2021/10/27/4 https://bugs.webkit.org/show_bug.cgi?id=231479 https://github.com/flatpak/flatpak/security/advisories/GHSA-67h7-w3jq-vh4q https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/H6MGXCX7P5AHWOQ6IRT477UKT7IS4DAD https:& •
