Assigner: MITRE

Description
An issue was discovered in mouse07410 asn1c thru 0.9.29 (2025-03-20) - a fork of vlm asn1c. In UPER (Unaligned Packed Encoding Rules), asn1c-generated decoders fail to enforce INTEGER constraints when the bound is positive and exceeds 32 bits in length, potentially allowing incorrect or malicious input to be processed.

Executive Summary

This vulnerability occurs in the mouse07410 asn1c decoder for UPER encoding, where INTEGER constraints are not properly enforced if the integer bound is positive and larger than 32 bits. This means the decoder may accept incorrect or malicious input that should have been rejected.

Impact Analysis

The impact of this vulnerability is that an attacker could supply malformed or malicious data that bypasses integer constraints, potentially causing the application to process invalid data, which could lead to unexpected behavior or security issues.
