CVE-2007-6114· NVD / CVE Program· CNA redhat

Multiple buffer overflows in Wireshark (formerly Ethereal) 0.99.0 through 0.99.6 allow remote attackers to cause a denial of service (crash)

Noroxi assessment

Priority: Plan (action score 42/100)

  • 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: 6.2% (FIRST EPSS); higher than 93.4% of all records.
  • No special conditions are required; it is repeatable.
  • Fixed version: wireshark (Debian:12) 0.99.7~pre1-1; ethereal (Debian:3.1) 0.10.10-2sarge10; wireshark (Debian:4.0) 0.99.4-5.etch.1.

Add it to your regular patch cycle. Upgrade to wireshark (Debian:12) 0.99.7~pre1-1; ethereal (Debian:3.1) 0.10.10-2sarge10; wireshark (Debian:4.0) 0.99.4-5.etch.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple buffer overflows in Wireshark (formerly Ethereal) 0.99.0 through 0.99.6 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) the SSL dissector or (2) the iSeries (OS/400) Communication trace file parser.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
