Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An exploitable out-of-bounds write exists in the Bzip2 parsing of the Lexmark Perspective Document Filters conversion functionality. A crafted Bzip2 document can lead to a stack-based buffer overflow causing an out-of-bounds write which under the right circumstance could potentially be leveraged by an attacker to gain arbitrary code execution.
