CVE-2025-46333

z2d is a pure Zig 2D graphics library. Versions of z2d after 0.5.1 and up to and including 0.6.0, when writing from one surface to another using z2d.compositor.StrideCompositor.run, and higher-level operations when the anti-aliasing mode is set to .default (such as Context.fill, Context.stroke, painter.fill, and painter.stroke), the source surface can be completely out-of-bounds on the x-axis, but not on the y-axis, by way of a negative offset. This results in an overflow of the value controlling the length of the stride. In non-safe optimization modes (consumers compiling with ReleaseFast or ReleaseSmall), this could potentially lead to invalid memory accesses or corruption.

This issue is patched in version 0.6.1. Users on an untagged version after v0.5.1 and before v0.6.1 are advised to update to address the vulnerability. Those still on Zig 0.13.0 are recommended to downgrade to v0.5.1.
