Summary

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.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Forced Integer Overflow
    This attack forces an integer variable to go out of range. The integer variable is often used as an offset such as size of memory allocation or similarly. The attacker would typically control the value of such variable and try to get it out of range. For instance the integer in question is incremented past the maximum possible value, it may wrap to become a very small, or negative number, therefore providing a very incorrect value which can lead to unexpected behavior. At worst the attacker can execute arbitrary code.
