Description

From Red Hat Security Advisory 2015:2155 :

Updated file packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The file command is used to identify a particular file according to the type of data the file contains. It can identify many different file types, including Executable and Linkable Format (ELF) binary files, system libraries, RPM packages, and different graphics formats.

Multiple denial of service flaws were found in the way file parsed certain Composite Document Format (CDF) files. A remote attacker could use either of these flaws to crash file, or an application using file, via a specially crafted CDF file. (CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3587)

Two flaws were found in the way file processed certain Pascal strings. A remote attacker could cause file to crash if it was used to identify the type of the attacker-supplied file. (CVE-2014-3478, CVE-2014-9652)

Multiple flaws were found in the file regular expression rules for detecting various files. A remote attacker could use these flaws to cause file to consume an excessive amount of CPU. (CVE-2014-3538)

Multiple flaws were found in the way file parsed Executable and Linkable Format (ELF) files. A remote attacker could use these flaws to cause file to crash, disclose portions of its memory, or consume an excessive amount of system resources. (CVE-2014-3710, CVE-2014-8116, CVE-2014-8117, CVE-2014-9653)

Red Hat would like to thank Thomas Jarosch of Intra2net AG for reporting the CVE-2014-8116 and CVE-2014-8117 issues. The CVE-2014-0207, CVE-2014-0237, CVE-2014-0238, CVE-2014-3478, CVE-2014-3479, CVE-2014-3480, CVE-2014-3487, CVE-2014-3710 issues were discovered by Francisco Alonso of Red Hat Product Security; the CVE-2014-3538 issue was discovered by Jan Kaluza of the Red Hat Web Stack Team

The file packages have been updated to ensure correct operation on Power little endian and ARM 64-bit hardware architectures. (BZ#1224667, BZ#1224668, BZ#1157850, BZ#1067688).

All file users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.
