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.

When mcpp application found multibyte characters when parsing the input file, it tries to show warning messages. The messages are shown via cwarn() function which further calls do_msg() with the error message itself formatted in printf-like format. The buffer containing the multibyte sequence is also passed as parameter for do_msg() which doesn't handle it gracefully. This causes a bu
