Synopsis

Moderate: file security and bug fix update

Type/Severity

Security Advisory: Moderate

Topic

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.

Description

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
Kaluža 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.
