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

CVE-2018-10919 [MEDIUM] CVE-2018-10919 samba: Confidential attribute disclosure via substring search
CVE-2018-10919 samba: Confidential attribute disclosure via substring search
When using custom LDAP attributes, Samba seems to recognize the searchFlags confidential flag on custom attributes and hides them from all non-admin users. However, the values of the attributes can still be guessed efficiently by brute forcing them one character after another in a wildcard search query.
