CVE-2019-12760

Priority
Description
** DISPUTED ** A deserialization vulnerability exists in the way parso
through 0.4.0 handles grammar parsing from the cache. Cache loading relies
on pickle and, provided that an evil pickle can be written to a cache
grammar file and that its parsing can be triggered, this flaw leads to
Arbitrary Code Execution. NOTE: This is disputed because "the cache
directory is not under control of the attacker in any common
configuration."
