CVE-2018-6331
If the state information is maliciously crafted, deserializing it could lead to code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Buck parser-cache command loads/saves state using Java serialized object. If the state information is maliciously crafted, deserializing it could lead to code execution. This issue affects Buck versions prior to v2018.06.25.01.
