(Archive::Zip: Virus detection evasion)


    Archive::Zip can be used by email scanning software (like amavisd-new) to
    uncompress attachments before virus scanning. By modifying the uncompressed
    size of archived files in the global header of the ZIP file, it is possible
    to fool Archive::Zip into thinking some files inside the archive have zero
    length.
  
Impact

    An attacker could send a carefully crafted ZIP archive containing a virus
    file and evade detection on some email virus-scanning software relying on
    Archive::Zip for decompression.
  
Workaround

    There is no known workaround at this time.

Solution: 
    All Archive::Zip users should upgrade to the latest version:
    # emerge --sync
    # emerge --ask --oneshot --verbose ">=dev-perl/Archive-Zip-1.14"
  

Risk factor : Low
