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.

CVE-2020-8623 bind: remotely triggerable assertion failure in pk11.c
As per upstream advisory:
If BIND is built with "--enable-native-pkcs11" then a specially crafted query for a zone signed with RSA can trigger an assertion failure.
An attacker that can reach a vulnerable system with a specially crafted query packet can trigger a crash.
To be vulnerable, the system must:
- be running BIND that was built with "--enable-native-pkcs11"
- be signing one or more zones with an RSA key
- be able to receive queries from a possible attacker
