A vulnerability was found in Hardlink up to 0.1.1 and classified as problematic. Affected by this issue is an unknown code. The manipulation with an unknown input leads to a out-of-bounds write vulnerability. Using CWE to declare the problem leads to CWE-787. The product writes data past the end, or before the beginning, of the intended buffer. Impacted is confidentiality, integrity, and availability. CVE summarizes:

Hardlink before 0.1.2 suffer from multiple stack-based buffer overflow flaws because of the way directory trees with deeply nested directories are processed. 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 the privileges of the user running the hardlink executable.

The bug was discovered 11/23/2011. The weakness was presented 11/26/2019. This vulnerability is handled as CVE-2011-3630 since 09/21/2011. Local access is required to approach this attack. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available.
