CWE ID Description
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 occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.

Executive Summary

This vulnerability is an integer overflow in the strip_return_port() function within the src/reqs.c file of Tinyproxy versions up to 1.11.2. An integer overflow occurs when an arithmetic operation attempts to create a numeric value that is outside the range that can be represented with a given number of bits, potentially leading to unexpected behavior or security issues.

Impact Analysis

The vulnerability can lead to a partial compromise of confidentiality and integrity, as indicated by the CVSS score impact metrics (Confidentiality: Low, Integrity: Low, Availability: None). This means an attacker could potentially exploit the integer overflow to gain limited unauthorized access or modify data, but it does not affect system availability.
