CVE-2021-42700: Inkscape Out-of-bounds Read

LowCVSS 3.3 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 13/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.80% (FIRST EPSS); higher than 57.2% of all records.
  • Someone with local access to the system can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
  • Fixed version: inkscape (Debian:12) 1.0-1.

Low priority for now. Upgrade to inkscape (Debian:12) 1.0-1 or later.
