CVE-2016-1945

23
FAUCET Score

CVE-2016-1945 describes a denial-of-service vulnerability in the nsZipArchive function of Mozilla Firefox versions prior to 44.0, also affecting related Mozilla and openSUSE products. This flaw arises from incorrect pointer usage during ZIP archive processing, potentially leading to unspecified other impacts beyond a denial of service. With a CVSS score of 8.8 (HIGH), it presents a significant risk, requiring user interaction (UI:R) but with low attack complexity (AC:L) and potential for high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). Despite its high severity, there is no evidence of active exploitation, no public exploit code available (Metasploit, Nuclei, ExploitDB), and it has received minimal community discussion or media coverage.
