CVE-2009-3383
Multiple unspecified vulnerabilities in the JavaScript engine in Mozilla Firefox 3.5.x before 3.5.4 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.34%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
