In versions 1.3.0 and 1.4.0, the `mulDiv(x, y, z)` function incorrectly handled cases where both the intermediate product $x * y$ and the divisor $z$ were negative. The logic assumed that if the intermediate product was negative, the final result must also be negative, neglecting the sign of $z$. This resulted in rounding being applied in the wrong direction for cases where both $x * y$ and $z$ were negative. The functions most at risk are `fixed_div_floor` and `fixed_div_ceil`, as they often use non-constant numbers as the divisor $z$ in `mulDiv`. This error is present in all signed `FixedPoint` and `SorobanFixedPoint` implementations, including `i64`, `i128`, and `I256`. Versions 1.3.1 and 1.4.1 contain a patch. No known workarounds for this issue are available."}], "lastModified": "2026-03-02T21:16:22.370", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:script3:soroban-fixed-point-math:1.3.0:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "BFBA3A8B-B607-418C-86A3-15AFD0F3A903"}, {"criteria": "cpe:2.3:a:script3:soroban-fixed-point-math:1.4.0:*:*:*:*:rust:*:*", "vulnerable": true, "matchCriteriaId": "48B58A8B-A909-4A41-B0F3-0E9CD0824255"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
