Rule Category

FILE-IDENTIFY -- Snort has detecte File Type indicators associated with packet data, which it will use to facilitate a flowbit, a method of stringing rules together. In a flowbit, one rule examines packets for file type indications, which it uses to switch rules pertaining to that file type from a dormant to active state in order to process the appropriate packets. File-type rules stay dormant to prevent alerts on innocent traffic. That same traffic, when contained in, for instance, a .doc file attached to an email, might be a threat and should be scanned.

Alert Message

FILE-IDENTIFY LZH archive file magic detected

Rule Explanation

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.
