Summary

Zen C is a systems programming language that compiles to human-readable GNU C/C11. Prior to version 0.4.4, a stack-based buffer overflow vulnerability in the Zen C compiler allows attackers to cause a compiler crash or potentially execute arbitrary code by providing a specially crafted Zen C source file (.zc) with excessively long struct, function, or trait identifiers.

Risk Assessment

Organizations may be exposed to system crashes or unauthorized code execution, leading to serious security implications. Exploiting this vulnerability could allow attackers to gain control over the system.

Recommendation

It is recommended to update to Zen C version v0.4.4 or later to apply the patch that addresses this vulnerability.
