CVE-2011-3630: Debian Linux

High severity, CVSS 8.8. EPSS: 2.7% chance of exploitation in the next 30 days.

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.

Affected products

• Debian Debian Linux: version 8.0 only; version 9.0 only; version 10.0 only
• Hardlink Project Hardlink: before 0.1.2 (fixed in 0.1.2)
• Red Hat Enterprise Linux: version 5.0 only; version 6.0 only
