CriticalCVSS 9.3 · v2.0—Proof of concept Fix available

Noroxi assessment

Priority: Plan (action score 40/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 10.4% (FIRST EPSS); higher than 95.8% of all records.
  • Fixed version: xulrunner (Debian:5.0) 1.9.0.7-0lenny2; MozillaFirefox (openSUSE:Tumbleweed) 50.1.0-1.1; seamonkey (Red Hat:enterprise_linux:2.1::as) 0:1.0.9-0.32.el2.

Add it to your regular patch cycle. Upgrade to xulrunner (Debian:5.0) 1.9.0.7-0lenny2; MozillaFirefox (openSUSE:Tumbleweed) 50.1.0-1.1; seamonkey (Red Hat:enterprise_linux:2.1::as) 0:1.0.9-0.32.el2 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The txMozillaXSLTProcessor::TransformToDoc function in Mozilla Firefox before 3.0.8 and SeaMonkey before 1.1.16 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an XML file with a crafted XSLT transform.
