Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (7.68%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

The http-index-format MIME type parser (nsDirIndexParser) in Firefox 3.x before 3.0.4, Firefox 2.x before 2.0.0.18, and SeaMonkey 1.x before 1.1.13 does not check for an allocation failure, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an HTTP index response with a crafted 200 header, which triggers memory corruption and a buffer overflow.
