Summary

CVE	CVE-2020-15703
State	PUBLIC
Assigner	[email protected]
Source Priority	CVE Program / NVD first with legacy fallback
Published	2020-10-31 04:15:00 UTC
Updated	2020-11-17 18:37:00 UTC
Description	There is no input validation on the Locale property in an apt transaction. An unprivileged user can supply a full path to a writable directory, which lets aptd read a file as root. Having a symlink in place results in an error message if the file exists, and no error otherwise. This way an unprivileged user can check for the existence of any files on the system as root.
