Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In mozjpeg DecompressScanlines, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

This issue and vector is similar to [RUSTSEC-2020-0029] of `rgb` crate which `mozjpeg` depends on. Affected versions of `mozjpeg` crate allow creating instances of any type `T` from bytes, and do not correctly constrain `T` to the types for which it is safe to do so. Examples of safety violation possible for a type `T`: * `T` contains a reference type, and it constructs a pointer to an invalid, arbitrary memory address. * `T` requires a safety and/or validity invariant for its construction that may be violated. The issue was fixed in 0.8.19 by using safer types and involving `rgb` dependency bump. [RUSTSEC-2020-0029]: https://rustsec.org/advisories/RUSTSEC-2020-0029.html
