Noroxi assessment

Priority: Monitor (action score 25/100)

  • 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: 15.2% (FIRST EPSS); higher than 96.7% of all records.
  • Special conditions such as timing or configuration are required.
  • Fixed version: devhelp (Red Hat:enterprise_linux:4::as) 0:0.9.2-2.4.5; devhelp-debuginfo (Red Hat:enterprise_linux:4::as) 0:0.9.2-2.4.5; devhelp-devel (Red Hat:enterprise_linux:4::as) 0:0.9.2-2.4.5.

Low priority for now. Upgrade to devhelp (Red Hat:enterprise_linux:4::as) 0:0.9.2-2.4.5; devhelp-debuginfo (Red Hat:enterprise_linux:4::as) 0:0.9.2-2.4.5; devhelp-devel (Red Hat:enterprise_linux:4::as) 0:0.9.2-2.4.5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The install function in Firefox 1.0.3 allows remote web sites on the browser's whitelist, such as update.mozilla.org or addon.mozilla.org, to execute arbitrary Javascript with chrome privileges, leading to arbitrary code execution on the system when combined with vulnerabilities such as CVE-2005-1476, as demonstrated using a javascript: URL as the package icon and a cross-site scripting (XSS) attack on a vulnerable whitelist site.
