Affected packages

• crates.io gfwx: < 0.3.0 → fixed in 0.3.0

Description

In the affected versions of this crate, ImageChunkMut unconditionally implements Send and Sync, allowing to create data races. This can result in a memory corruption or undefined behavior when non thread-safe types are moved and referenced across thread boundaries. The flaw was corrected in commit e7fb2f5 by adding T: Send bound to the Send impl and adding T: Sync bound to the Sync impl.
