  script_tag(name:"insight", value:"Multiple security issues have been found in file, a tool/library to determine a file type. Processing a malformed file could result in denial of service. Most of the changes are related to parsing ELF files.

As part of the fixes, several limits on aspects of the detection were added or tightened, sometimes resulting in messages like recursion limit exceeded or too many program header sections.

To mitigate such shortcomings, these limits are controllable by a new '-R'/'--recursion' parameter in the file program. Note: A future upgrade for file in squeeze-lts might replace this with the '-P' parameter to keep usage consistent across all distributions.

CVE-2014-8116

The ELF parser (readelf.c) allows remote attackers to cause a denial of service (CPU consumption or crash).

CVE-2014-8117

softmagic.c does not properly limit recursion, which allows remote attackers to cause a denial of service (CPU consumption or crash).
