CVE-2016-4336

Status: ModifiedCritical (9.8)—

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.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
