CVE-2011-3631 Information

Description

Hardlink before 0.1.2 has multiple integer overflows leading to heap-based buffer overflows because of the way string lengths concatenation is done in the calculation of the required memory space to be used. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it leading to hardlink executable crash or potentially arbitrary code execution with user privileges.
