hardlink: Multiple integer overflows, when adding string lengths
Published Nov 26, 2019
8.8
HIGHCVSS 3.1
EPSS 2.69%
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.
