CVE-2014-1420 – Insecure temp file usage in Ubuntu UI toolkit

https://notcve.org/view.php?id=CVE-2014-1420

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. En escritorio, StateSaver de Ubuntu UI Toolkit serializaría datos en archivos tmp/ que un atacante podría usar para exponer datos potencialmente confidenciales. • http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-toolkit/staging/revision/1182 https://launchpad.net/bugs/1348241 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-502: Deserialization of Untrusted Data •
