HIGH 7.5EPSS 5.91%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (5.91%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected. The malicious input can trigger an OOME and so a DoS attack
