https://notcve.org/view.php?id=CVE-2012-2737

The user_change_icon_file_authorized_cb function in /usr/libexec/accounts-daemon in AccountsService before 0.6.22 does not properly check the UID when copying an icon file to the system cache directory, which allows local users to read arbitrary files via a race condition. La función de user_change_icon_file_authorized_cb en /usr/libexec/accounts-daemon de las cuentas en AccountsService anterior a v0.6.22 no comprueba correctamente el UID al copiar un archivo de icono en el directorio de memoria caché del sistema, lo que permite a usuarios locales leer ficheros arbitrarios a través de una condición de carrera. • http://cgit.freedesktop.org/accountsservice/commit/?id=26213aa0e0d8dca5f36cc23f6942525224cbe9f5 http://cgit.freedesktop.org/accountsservice/commit/?id=27f3d93a82fde4f6c7ab54f3f008af04f93f9c69 http://cgit.freedesktop.org/accountsservice/commit/?id=4c5b12e363410e490e776e4b4a86dcce157a543d http://cgit.freedesktop.org/accountsservice/commit/?id=bd51aa4cdac380f55d607f4ffdf2ab3c00d08721 http://lists.fedoraproject.org/pipermail/package-announce/2012-July/083359.html http://osvdb.org/83398 http://secunia.com/advisories/49695 http://secunia.com/advisories/49759& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
