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`.

"value": "z2d es una librería de gráficos Zig 2D pura. En la versión 0.6.0, al escribir de una superficie a otra usando `z2d.compositor.StrideCompositor.run`, la superficie de origen puede estar completamente fuera de los límites en el eje x (pero no en el eje y) debido a un desplazamiento negativo. Esto provoca un desbordamiento del valor que controla la longitud de la zancada. En modos de optimización no seguros (consumidores que compilan con `ReleaseFast` o `ReleaseSmall`), esto podría provocar accesos no válidos a memoria o corrupción. Este problema se solucionó en la versión 0.6.1."
