transpose: Buffer overflow due to integer overflow

Moderate severity GitHub Reviewed Published Apr 5, 2024 to the GitHub Advisory Database • Updated Jul 28, 2025

Package

cargo transpose (Rust)

Affected versions

>= 0.1.0, < 0.2.3

Patched versions

0.2.3

Description

Given the function transpose::transpose:

fn transpose<T: Copy>(input: &[T], output: &mut [T], input_width: usize, input_height: usize)

The safety check input_width * input_height == output.len() can fail due to input_width * input_height overflowing in such a way that it equals output.len().
As a result of failing the safety check, memory past the end of output is written to. This only occurs in release mode since * panics on overflow in debug mode.

Exploiting this issue requires the caller to pass input_width and input_height arguments such that multiplying them overflows, and the overflown result equals the lengths of input and output slices.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow. Learn more on MITRE.

Integer Overflow or Wraparound

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 can introduce other weaknesses when the calculation is used for resource management or execution control. Learn more on MITRE.
