CVE-2022-38725
Microsoft · Published August 7, 2026
CVSS v3.1
HIGHDescription
An integer overflow in the RFC3164 parser in One Identity syslog-ng 3.0 through 3.37 allows remote attackers to cause a Denial of Service via crafted syslog input that is mishandled by the tcp or network function. syslog-ng Premium Edition 7.0.30 and syslog-ng Store Box 6.10.0 are also affected.. 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.
