CVE-2017-3145: Improper fetch cleanup sequencing in the resolver can cause named to crash

HighCVSS 7.5 · v3.1—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: 27.7% (FIRST EPSS); higher than 98.1% 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: bind (Alpine:v3.10) 9.11.2_p1-r0; bind (Alpine:v3.4) 9.10.6_p1-r0; bind9 (Debian:12) 1:9.11.2.P1-1.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to bind (Alpine:v3.10) 9.11.2_p1-r0; bind (Alpine:v3.4) 9.10.6_p1-r0; bind9 (Debian:12) 1:9.11.2.P1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. Affects BIND 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, 9.12.0a1 to 9.12.0rc1.
