Vigil@nce - Fine Free file: unreachable memory reading via Pascal
February 2015 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 Pascal
file, in order to trigger a denial of service.
Impacted products: Debian, PHP, Unix (platform)
Severity: 1/4
Creation date: 05/02/2015
DESCRIPTION OF THE VULNERABILITY
The Fine Free file (libmagic) program analyzes files, in order to
automatically recognize their type.
However, during the analysis of a Pascal file, libmagic tries to
read a memory area which is not reachable, which triggers a fatal
error.
An attacker can therefore force Fine Free file to analyze a
malicious Pascal file, in order to trigger a denial of service.
