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.
