XML Entity Expansion (Billion Laughs Attack) on Pippo 1.12.0 results in Denial of Service.Entities are created recursively and large amounts of heap memory is taken.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.44%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
XML Entity Expansion (Billion Laughs Attack) on Pippo 1.12.0 results in Denial of Service.Entities are created recursively and large amounts of heap memory is taken. Eventually, the JVM process will run out of memory. Otherwise, if the OS does not bound the memory on that process, memory will continue to be exhausted and will affect other processes on the system.
