CVE-2019-10063
flatpak: Sandbox bypass via IOCSTI (incomplete fix for CVE-2017-5226)
Sévérité par source
Le label propre à Trivy est CRITICAL. Critique selon NVD. Plus basse selon Red Hat (élevée), Amazon (élevée), Oracle (élevée), Ubuntu (moyenne).
Description
Flatpak before 1.0.8, 1.1.x and 1.2.x before 1.2.4, and 1.3.x before 1.3.1 allows a sandbox bypass. Flatpak versions since 0.8.1 address CVE-2017-5226 by using a seccomp filter to prevent sandboxed apps from using the TIOCSTI ioctl, which could otherwise be used to inject commands into the controlling terminal so that they would be executed outside the sandbox after the sandboxed app exits. This fix was incomplete: on 64-bit platforms, the seccomp filter could be bypassed by an ioctl request number that has TIOCSTI in its 32 least significant bits and an arbitrary nonzero value in its 32 most significant bits, which the Linux kernel would treat as equivalent to TIOCSTI.
