CVE-2018-8015
The impact of this bug is most likely denial-of-service against software that uses the ORC file parser.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.23%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
In Apache ORC 1.0.0 to 1.4.3 a malformed ORC file can trigger an endlessly recursive function call in the C++ or Java parser. The impact of this bug is most likely denial-of-service against software that uses the ORC file parser. With the C++ parser, the stack overflow might possibly corrupt the stack.
