CVE-2008-2419: Mozilla Firefox

Medium severity, CVSS 4.3. EPSS: 6.6% chance of exploitation in the next 30 days.

Mozilla Firefox 2.0.0.14 allows remote attackers to cause a denial of service (heap corruption and application crash) or possibly execute arbitrary code by triggering an error condition during certain Iframe operations between a JSframe write and a JSframe close, as demonstrated by an error in loading an empty Java applet defined by a 'src="javascript:"' sequence.

Affected products
