CVE-2011-3631
CVSS v2.0
6.8
Média
| Vetor | AV:N/AC:M/Au:N/C:P/I:P/A:P |
Name of the Vulnerable Software and Affected Versions
Hardlink versions prior to 0.1.2
Description
The issue arises from multiple integer overflows that lead to heap-based buffer overflows due to the way string lengths are concatenated in the calculation of the required memory space. A remote attacker could provide a specially-crafted directory tree and trick the local user into consolidating it, potentially leading to a hardlink executable crash or arbitrary code execution with user privileges.
Recommendations
For versions prior to 0.1.2, update to version 0.1.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of hardlink to prevent consolidation of potentially malicious directory trees until a patch is applied.
