Ubuntu enhances system integrity in a Medium notice, addressing various vulnerabilities. Crucial for operational reliability.
An update for file is now available for Red Hat Enterprise Linux 6

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

Summary

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.
Security Fix(es):
* 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)
* A denial of service flaw was found in the way file parsed certain Composite Document Format (CDF) files. A remote attacker could use this flaw to crash file via a specially crafted CDF file. (CVE-2014-3587)
* 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-2014-9620, CVE-2014-9653)
Red Hat would like to thank Thomas Jarosch (Intra2net AG) for reporting CVE-2014-8116 and CVE-2014-8117. The CVE-2014-3538 issue was discovered by Jan Kaluža (Red Hat Web Stack Team) and the CVE-2014-3710 issue was discovered by Francisco Alonso (Red Hat Product Security).
