Descriptions

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. StateSaver también abriría archivos sin el indicador O_EXCL. Un atacante podría explotar esto para iniciar un ataque de enlace simbólico, aunque esto está parcialmente mitigado por las restricciones de enlaces simbólicos y físicos en Ubuntu. Corregido en versiones 1.1.1188 +14.10.20140813.4-0ubuntu1
