CVE-2016-9388

18
FAUCET Score

CVE-2016-9388 is a denial-of-service vulnerability affecting the JasPer image processing library, specifically in the ras_getcmap function within ras_dec.c. This flaw allows remote attackers to trigger an assertion failure by providing a specially crafted image file, impacting products like Canonical Ubuntu Linux and JasPer Project's JasPer. Rated Medium severity (CVSS 5.5), successful exploitation requires user interaction (UI:R) and local access (AV:L), leading to high availability impact (A:H). There is no evidence of active exploitation, no public exploit code (Metasploit, Nuclei, ExploitDB), and minimal community discussion or media coverage, suggesting it is not a widely targeted vulnerability.
