OverlayFS in the Linux kernel before 3.0.0-16.28, as used in Ubuntu 10.0.4 LTS and 11.10, is missing inode security checks which could allow attackers to bypass security restrictions and perform unauthorized actions. OverlayFS en el kernel de Linux versiones anteriores a 3.0.0-16.28, como es usado en Ubuntu versiones 10.0.4 LTS y 11.10, carece de verificaciones de seguridad de inode que podrían permitir a atacantes omitir las restricciones de seguridad y llevar a cabo acciones no autorizadas. • https://www.exploit-db.com/exploits/36571 http://www.openwall.com/lists/oss-security/2012/01/17/11 http://www.ubuntu.com/usn/USN-1363-1 http://www.ubuntu.com/usn/USN-1364-1 http://www.ubuntu.com/usn/USN-1384-1 https://access.redhat.com/security/cve/cve-2012-0055 https://bugs.launchpad.net/ubuntu/+source/linux/+bug/915941 https://bugzilla.suse.com/show_bug.cgi?id=CVE-2012-0055 • CWE-862: Missing Authorization •
