CVE-2015-8704: apl_42.c in ISC BIND 9.x before 9.9.8-P3, 9.9.x, and 9.10.x before 9.10.3-P3 allows remote authenticated users to cause a denial of service…

MediumCVSS 6.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 20.6% (FIRST EPSS); higher than 97.5% of all records.
  • Anyone who can reach it over the internet can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: bind9 (Debian:12) 1:9.10.3.dfsg.P4-6; bind9 (Debian:6.0) 1:9.7.3.dfsg-1~squeeze19; bind9 (Debian:7) 1:9.8.4.dfsg.P1-6+nmu2+deb7u9.

Low priority for now. Upgrade to bind9 (Debian:12) 1:9.10.3.dfsg.P4-6; bind9 (Debian:6.0) 1:9.7.3.dfsg-1~squeeze19; bind9 (Debian:7) 1:9.8.4.dfsg.P1-6+nmu2+deb7u9 or later.
