CVE-2016-2335 P7ZIP vulnerabilities
Title: P7ZIP vulnerabilities
Summary: p7zip could be made to crash or run programs as your login if it
opened a specially crafted file.
It was discovered that p7zip did not correctly handle certain malformed
archives. If a user or automated system were tricked into processing a specially
crafted archive with p7zip, then p7zip could be made to crash, possibly leading
to abitrary code execution.
Instructions: In general, a standard system update will make all the necessary changes.

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 ad
