HIGHCVSS 8.8/10EPSS 2.69%

Last modified

CVE-2011-3631 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. 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.. EPSS estimates a 2.69% chance of exploitation in the next 30 days.
