CVE-2025-46333
No affected components available
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.
The vulnerability requires local access to the device to be exploited. It is difficult for an attacker to exploit this vulnerability and may require special conditions. An attacker needs basic access or low-level privileges.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
