Published Nov 26, 2019CWE-787EPSS 2.66%

Overview

CVE-2011-3630 is a high-severity vulnerability. It was published on November 26, 2019 and has a CVSS 3.1 base score of 8.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.8, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
