Noroxi assessment
Priority: Monitor (action score 22/100)
- Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 7.5% (FIRST EPSS); higher than 94.6% of all records.
- No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.
Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it
Primary sources: NVD · CVE.org · FIRST EPSS
tcpdump, Ethereal, and other sniffer packages allow remote attackers to cause a denial of service via malformed DNS packets in which a jump offset refers to itself, which causes tcpdump to enter an infinite loop while decompressing the packet.
