CVE-2023-29581: yasm 1.3.0.55.g101bc has a segmentation violation in the function delete_Token at modules/preprocs/nasm/nasm-pp.c. NOTE: although a libyasm application could become unavailable if this were exploited, the vendor's position is that there is no security relevance because there is either supposed to be input validation before data reaches libyasm, or a sandbox in which the application runs.

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.
