RedHat: RHSA-2016-0760:01 Moderate: file security, bug fix,
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).
