Debian Security Advisory
DLA-131-1 file -- LTS security update
- Date Reported:
- 09 Jan 2015
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 773148.
In Mitre's CVE dictionary: CVE-2014-8116, CVE-2014-8117.
- More information:
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 exceededor
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.
The ELF parser (readelf.c) allows remote attackers to cause a denial of service (CPU consumption or crash).
softmagic.c does not properly limit recursion, which allows remote attackers to cause a denial of service (CPU consumption or crash).
(no identifier has been assigned so far)
out-of-bounds memory access
For Debian 6
Squeeze, these issues have been fixed in file version 5.04-5+squeeze9
