Heap-based buffer overflow in the NCompress::NShrink::CDecoder::CodeReal method in 7-Zip before 18.00 and p7zip allows remote attackers to cause a denial of service (out-of-bounds write) or potentially execute arbitrary code via a crafted ZIP archive.

Security readout for executives and security teams

A malicious ZIP archive can trigger a heap buffer overflow in 7-Zip before 18.00 and p7zip. If a user or automated system opens or extracts the archive, impact could range from a crash to possible code execution. Treat exposure seriously wherever untrusted archives are processed. Systems are most exposed when endpoints, file gateways, mail scanners, CI jobs, or backend services use vulnerable 7-Zip or p7zip versions to inspect or extract untrusted ZIP archives. Prioritize remediation for systems that receive external files or process email, uploads, or customer archives. Business risk is highest where archive parsing is automated and runs with broad file or network access. Mitigation focus: Upgrade 7-Zip to 18.00 or later where applicable.; Apply Debian or Ubuntu p7zip security updates from the cited advisories.; Restrict vulnerable archive processing of untrusted ZIP files until updated..
