Apr 26, 2018
- Cisco Email Security Appliance
Known Affected Releases
8.0.1-023 8.5.6-074 9.1.1-051
Symptom: Some Office 2010 and above documents, such as .docx or .xslx files may be detected incorrectly as ZIP files by the "Attachment File Info" -> "File type is" content filter condition or the 'attachment-filetype' message filter rule. Conditions: This has been identified as caused by files whose internal file order is non-standard, where the '[Content_Types].xml' file is not the first file in the archive.
