Description
This security bulletin contains information about 1 security vulnerability.
1) Heap-based buffer overflow (CVE-ID: CVE-2025-47436)
The vulnerability allows a local privileged user to cause memory corruption.
The vulnerability exists due to a boundary error in the ORC C++ LZO decompression logic, where specially crafted malformed ORC files can cause the decompressor to allocate a 250-byte buffer but then attempts to copy 295 bytes into it. A local privileged user can pass specially crafted data to the application, trigger a heap-based buffer overflow and cause memory corruption.
