Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow in the yuv_ensure_buffer function. An attacker can achieve arbitrary code execution or cause a denial of service by triggering a failure in the winpr_aligned_recalloc process, leading to a mismatch between buffer dimensions and allocated memory, which results in a heap-based out-of-bounds write.
