CVE-2017-17083: In Wireshark 2.4.0 to 2.4.2 and 2.2.0 to 2.2.10, the NetBIOS dissector could crash.

HighCVSS 7.5 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 2.7% (FIRST EPSS); higher than 86.2% 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: wireshark (Alpine:v3.10) 2.4.3-r0; wireshark (Alpine:v3.5) 2.2.11-r0; wireshark (Debian:12) 2.4.3-1.

Low priority for now. Upgrade to wireshark (Alpine:v3.10) 2.4.3-r0; wireshark (Alpine:v3.5) 2.2.11-r0; wireshark (Debian:12) 2.4.3-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In Wireshark 2.4.0 to 2.4.2 and 2.2.0 to 2.2.10, the NetBIOS dissector could crash. This was addressed in epan/dissectors/packet-netbios.c by ensuring that write operations are bounded by the beginning of a buffer.
