Title: OpenJPEG vulnerabilities
Summary: Several security issues were fixed in OpenJPEG.
Sebastian Poeplau discovered that OpenJPEG incorrectly handled certain inputs.
If a user or an automated system were tricked into opening a specially crafted
input file, a remote attacker could possibly use this issue to cause a denial
of service or execute arbitrary code. This issue only affected Ubuntu 18.04

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
