Integer underflow in lzhsr.dll in Autonomy KeyView, as used in IBM Lotus Notes before 8.5.2 FP3, allows remote attackers to execute arbitrary code via a crafted header in a .lzh attachment that triggers a stack-based buffer overflow, aka SPR PRAD88MJ2W.

Security readout for executives and security teams

This flaw affects IBM Lotus Notes before 8.5.2 FP3 when handling LZH email attachments. A malicious attachment could crash vulnerable parsing code and potentially run attacker-controlled code. Business risk is highest where legacy Notes clients still open or preview untrusted attachments. Exposure appears limited to IBM Lotus Notes versions before 8.5.2 FP3, based on the provided record. The bundle does not provide CPEs, CVSS scoring, or a complete product matrix. Treat any remaining legacy Notes endpoint capable of rendering LZH attachments as the primary concern. Prioritize if legacy IBM Lotus Notes remains in use. The vulnerability is old, but the impact is arbitrary code execution through an email attachment path. If Notes has been retired or all clients are at 8.5.2 FP3 or later, urgency drops substantially. Mitigation focus: Upgrade IBM Lotus Notes to 8.5.2 FP3 or later where still deployed.; Review IBM advisory swg21500034 for vendor-specific remediation details.; Restrict or quarantine .lzh attachments while patch status is being confirmed..
