CVE-2017-6369
Insufficient checks in the UDF subsystem in Firebird 2.5.x before 2.5.7 and 3.0.x before 3.0.2 allow remote authenticated users to execute code by using a 'system' entrypoint from fbudf.so.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.30%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
