Title: Go vulnerabilities
Summary: Several security issues were fixed in Go.
It was discovered that Go did not properly manage memory under certain
circumstances. An attacker could possibly use this issue to cause a panic
resulting in a denial of service. This issue only affected golang-1.19 on
Ubuntu 22.10. (CVE-2022-41724, CVE-2023-24534, CVE-2023-24537)

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.

golang: html/template: improper handling of empty HTML attributes
Templates containing actions in unquoted HTML attributes (e.g. "attr={{.}}") executed with empty input can result in output with unexpected results when parsed due to HTML normalization rules. This may allow injection of arbitrary attributes into tags.
A flaw was found in golang. Templates containing actions in unquoted HTML attributes, for example, "attr={{.}}") executed with empty input, could result in output that has unexpected results when parsed due to HTML normalization rules. This issue may allow the injection of arbitrary attributes into tags.
Statement: For Red Hat Enterprise Linux,
* Conmon uses go in unit testing, but not functionally in the package. Go is used only in test files, not in the actual code. Thus,
