A vulnerability was found in Hardlink up to 0.1.1. It has been classified as critical. This affects an unknown code block. The manipulation with an unknown input leads to a integer overflow vulnerability. CWE is classifying the issue as CWE-190. The product performs a calculation that can produce an integer overflow or wraparound, when the logic assumes that the resulting value will always be larger than the original value. This can introduce other weaknesses when the calculation is used for resource management or execution control. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The bug was discovered 11/23/2011. The weakness was shared 11/26/2019. This vulnerability is uniquely identified as CVE-2011-3631 since 09/21/2011. Attacking locally is a requirement. The requirement for exploitation is a authentication. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 57069 (Fedora 15 : hardlink-1.0-12.fc15 (2011-14753)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks and running in the context l.

Upgrading to version 0.1.2 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the vulnerability database at Tenable (57069). The entries 146318 and 146320 are related to this item.
