| VCID-a2qm-vkc3-qkd5 | ImageMagick has Undefined Behavior (function-type-mismatch) in CloneSplayTree ## Summary - **Target:** ImageMagick (commit `ecc9a5eb456747374bae8e07038ba10b3d8821b3`) - **Type:** Undefined Behavior (function-type-mismatch) in splay tree cloning callback - **Impact:** Deterministic abort under UBSan (DoS in sanitizer builds).

ConstantString has a different signature (`char *ConstantString(const char *)`). Calling through the mismatched function type is undefined behavior in C and triggers UBSan’s function-type-mismatch. The path is exercised during coalescing: CloneImage → CloneImageProfiles → CloneSplayTree. Scope Reproduces with a minimal, sanitizer-instrumented, PNG-enabled build and delegates disabled (policy.xml), suggesting the issue is in MagickCore rather than external delegates. Suggested fix (sketch) Use a wrapper that matches the expected callback prototype, or adjust the splay-tree callback typedef for const-correctness. For example: static void *CloneStringShim(const void *p) { return (void *) ConstantString((const char *) p); } /* When setting splay-tree clone_value, use CloneStringShim instead of ConstantString. */ Alternatively, update the clone callback typedefs to use const void* consistently (and return void*) and ensure callers pass a correctly typed wrapper.
