SANE protocol dissector infinite loop in Wireshark 4.6.0 to 4.6.4 and 4.4.0 to 4.4.14 allows denial of service
AI Analysis
Technical Summary
This vulnerability in Wireshark's SANE protocol dissector causes an infinite loop due to an unreachable exit condition. Affected versions include 4.6.0 through 4.6.4 and 4.4.0 through 4.4.14. Exploitation results in denial of service by making Wireshark unresponsive. The CVSS 3.1 base score is 5.5, reflecting a medium severity with local attack vector, low complexity, no privileges required, user interaction required, unchanged scope, and impact limited to availability.
Potential Impact
Successful exploitation leads to denial of service by causing Wireshark to enter an infinite loop, making it unresponsive. There is no impact on confidentiality or integrity. No known exploits are reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the Wireshark Foundation advisory for current remediation guidance. Until a fix is available, avoid analyzing untrusted SANE protocol traffic or use alternative tools. Monitor official Wireshark channels for updates.
