Excessive memory consumption in MS-WSP dissector in Wireshark 3.4.0 to 3.4.4 and 3.2.0 to 3.2.12 allows denial of service via packet injection or crafted capture file
A flaw was found in wireshark. A memory leak in the MS-WSP dissector allows an attacker to crash an application which uses wireshark due to excessive memory allocation. The attacker can trigger the flaw by injecting special packets onto the wire or by convincing a victim user into opening a malformed packet trace file. The highest threat from this vulnerability is to application availability.

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.
