SB20261110258 - Integer overflow in onnx

Description

This security bulletin contains information about 1 vulnerability.

1) Integer overflow (CVE-ID: N/A)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 5.1 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote attacker to produce incorrect or negative inferred dimensions, compromising the integrity of shape-inference results.

The vulnerability exists due to unchecked signed integer arithmetic and narrowing of 64-bit dimensions to 32-bit integers in ONNX MathOpTwoIntegers() and Concat when performing shape inference. A remote attacker can supply a crafted model through a local library API or file boundary with overflowing Add, Sub, or Mul operations when data_prop=True, or oversized Concat dimensions or sums during ordinary shape inference, to produce incorrect dimension information.

Remediation
