CVE-2018-6616

20
FAUCET Score

CVE-2018-6616 describes a denial-of-service vulnerability in OpenJPEG 2.3.0, specifically due to excessive iteration in the opj_t1_encode_cblks function, which can be triggered by a crafted BMP file. This medium-severity vulnerability (CVSS 5.5) allows remote attackers to impact system availability (A:H) with low attack complexity (AC:L) and requires user interaction (UI:R) for exploitation. While affecting products from Canonical, Debian, Oracle, and UCLouvain, there is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
