Message-Id: <200811241634.08610.ludwig.nussel@suse.de> Date: Mon, 24 Nov 2008 16:34:07 +0100 From: Ludwig Nussel <ludwig.nussel@...e.de> To: cve@...re.org Cc: oss-security@...ts.openwall.com Subject: CVE Request: VirtualBox tmp file issue Hi, http://www.virtualbox.org/wiki/Changelog: VirtualBox 2.0.6 - Linux/Solaris/Darwin hosts: verify permissions in /tmp/vbox-$USER-ipc These changes match that description: http://www.virtualbox.org/changeset?new=trunk%2Fsrc%2Flibs%2Fxpcom18a4%2Fipc%2Fipcd%2Fdaemon%2Fsrc%2FipcdUnix.cpp%4013810&old=trunk%2Fsrc%2Flibs%2Fxpcom18a4%2Fipc%2Fipcd%2Fdaemon%2Fsrc%2FipcdUnix.cpp%407049 VirtualBox uses /tmp/vbox-$USER-ipc to store a socket and a lock file. The lock file is truncated after a simple open call. AFAICS creating /tmp/vbox-$USER-ipc before the victim starts VirtualBox could therefore be exploited to create files as the victim or truncate files of the victim. cu Ludwig -- (o_ Ludwig Nussel //\ V_/_ http://www.suse.de/ SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nuernberg)
