HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 38/100)

  • 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: 25.7% (FIRST EPSS); higher than 98% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: bind9 (Debian:12) 1:9.9.3.dfsg.P2-1; bind9 (Debian:7) 1:9.8.4.dfsg.P1-6+nmu2+deb7u12; bind (Red Hat:enterprise_linux:5::client) 30:9.3.6-25.P1.el5_11.10.

Low priority for now. Upgrade to bind9 (Debian:12) 1:9.9.3.dfsg.P2-1; bind9 (Debian:7) 1:9.8.4.dfsg.P1-6+nmu2+deb7u12; bind (Red Hat:enterprise_linux:5::client) 30:9.3.6-25.P1.el5_11.10 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

ISC BIND 9.1.0 through 9.8.4-P2 and 9.9.0 through 9.9.2-P2 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via malformed options data in an OPT resource record.
