Overview
Affected versions of this package are vulnerable to Use After Free in the png_set_tRNS and png_set_PLTE functions, where a heap-allocated buffer is aliased between two structures with independent lifetimes. An attacker can cause memory corruption or potentially execute arbitrary code by triggering a use-after-free condition through crafted calls that free memory while leaving dangling pointers, followed by subsequent operations that dereference or write to the freed memory.
