Squashfs is intended for general read-only filesystem use, for archival use (i.e. in cases where a .tar.gz file may be used), and in constrained block device/memory systems (e.g. embedded systems) where low overhead is needed. </p> </background> <description> <p>Multiple vulnerabilities have been discovered in SQUASHFS. Please review the CVE identifiers referenced below for details. </p> </description> <impact type="normal"> <p>A remote attacker could entice a user to open a specially crafted .sqsh file using unsquashfs; possibly resulting in the execution of arbitrary code with the privileges of the process, or a Denial of Service condition. </p> </impact> <workaround> <p>There is no known workaround at this time.</p> </workaround> <resolution> <p>All squashfs-tools users should upgrade to the latest version:</p> <code> # emerge --sync # emerge --ask --oneshot --verbose ">=sys-fs/squashfs-tools-4.3" </code> </resolution> <references> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4024">CVE-2012-4024</uri> <uri link="https://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4025">CVE-2012-4025</uri> </references> <metadata tag="requester" timestamp="2016-11-29T23:27:04Z">whissi</metadata> <metadata tag="submitter" timestamp="2016-12-14T10:21:21Z">whissi</metadata> </glsa>
