CVE-2019-13226 (GCVE-0-2019-13226)

Vulnerability from cvelistv5 – Published: 2019-07-04 11:32 – Updated: 2024-08-04 23:49

Summary

deepin-clone before 1.1.3 uses a predictable path /tmp/.deepin-clone/mount/<block-dev-basename> in the Helper::temporaryMountDevice() function to temporarily mount a file system as root. An unprivileged user can prepare a symlink at this location to have the file system mounted in an arbitrary location. By winning a race condition, the attacker can also enter the mount point, thereby preventing a subsequent unmount of the file system.

Severity

No CVSS data available.
