Sophos Anti-Virus Unable to Scan PDFs with Large Cross-Reference Tables.
The most recent Sophos anti-virus scanning engine imposes a maximum limit to the
number of entries in a PDF’s cross-reference tables to avoid malformed files from
using too much memory. The scanning engine returns “unscannable” for PDFs that
exceed the maximum limit even if they are not malformed. Cisco IronPort is working
with Sophos to resolve this issue in a future Sophos engine update.
