CVE-2016-9296: A null pointer dereference bug affects the 16.02 and many old versions of p7zip.

A null pointer dereference bug affects the 16.02 and many old versions of p7zip. A lack of null pointer check for the variable folders.PackPositions in function CInArchive::ReadAndDecodePackedStreams in CPP/7zip/Archive/7z/7zIn.cpp, as used in the 7z.so library and in 7z applications, will cause a crash and a denial of service when decoding malformed 7z files.

Security readout for executives and security teams

CVE-2016-9296 is a crash bug in p7zip 16.02 and many older versions. A specially malformed 7z archive can make affected 7z components crash, causing denial of service where archive processing is part of a business workflow. Exposure is most likely where p7zip 16.02 or older p7zip builds process untrusted 7z archives, including automated extraction, upload handling, or scanning workflows. The source bundle does not provide precise vendor CPEs or a fixed version. Treat this as a workflow availability issue, not confirmed remote code execution. Prioritize internet-facing or automated archive-processing services first, because a crash can disrupt file intake, scanning, or user upload operations. Mitigation focus: Inventory systems and containers using p7zip or 7z.so.; Check operating system or vendor package guidance for fixed p7zip builds.; Reduce or isolate processing of untrusted 7z archives until addressed..
