Comment 2 for bug 553266

After further discussion, bb#1826 should probably be included:
08:30 < mdeslaur> well, it is security relevant in a clamav context
08:30 < mdeslaur> virus laden email hides in cabinet files
08:30 < mdeslaur> they make them slightly corrupted so AV scanners can't open them
08:30 < mdeslaur> this makes clamav open more corrupted cabinet files, so it can scan the files inside
08:31 < mdeslaur> so it's security relevant in a "lets less viruses go though" way
08:33 < jdstrand> will clamav reject it if it is malformed?
08:34 < mdeslaur> it depends on what the software that uses clamav does
08:34 < mdeslaur> It's usually configurable
08:36 < jdstrand> ScottK: based on mdeslaur's comments, let's include it for those people who accept attachments that can't be decompressed
