Vigil@nce - Fine Free file: denial of service via ELF Strings
December 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can force Fine Free file to analyze a malicious ELF
file, in order to trigger a denial of service.
Impacted products: Unix (platform)
Severity: 1/4
Creation date: 17/12/2014
DESCRIPTION OF THE VULNERABILITY
The Fine Free file (libmagic) program analyzes files, in order to
automatically recognize their type.
However, an ELF file containing large strings consumes a lot of
resources.
An attacker can therefore force Fine Free file to analyze a
malicious ELF file, in order to trigger a denial of service.
