What is CVE-2014-1420?
CVE-2014-1420 is a low-severity path traversal vulnerability in Canonical ubuntu-ui-toolkit, published on 10 Sep 2020. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
On desktop, Ubuntu UI Toolkit's StateSaver would serialise data on tmp/ files which an attacker could use to expose potentially sensitive data. StateSaver would also open files without the O_EXCL flag. An attacker could exploit this to launch a symlink attack, though this is partially mitigated by symlink and hardlink restrictions in Ubuntu. Fixed in 1.1.1188+14.10.20140813.4-0ubuntu1.
