CVE-2021-4184 [HIGH] CWE-835 wireshark: BitTorrent DHT dissector infinite loop
wireshark: BitTorrent DHT dissector infinite loop
Infinite loop in the BitTorrent DHT dissector in Wireshark 3.6.0 and 3.4.0 to 3.4.10 allows denial of service via packet injection or crafted capture file
An infinite-loop flaw was found in Wireshark's DHT dissector module. This flaw allows an attacker with local network access to pass specially crafted capture files, causing an application to halt, crash or go into an infinite loop.

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified, we will update the CVE to reflect this.
