> A heap-based buffer overflow vulnerability was identified in Apache ORC's C++ LZO decompression implementation. Specially crafted malformed ORC files can cause the decompressor to allocate a 250-byte buffer followed by a 295-byte copy, leading to memory corruption. This patch incorporates fix P11 which corrects the unsafe memory copy, mitigating the vulnerability.
