After nearly 20 years of security news this service is discontinued. Some reasons are the very high number of vulnerabilities combined with automatically updating systems. So the necessity of this service is depreciated. We hope that you understand this decision.
Please visit us also at!

Most of the links lead to the corresponding files at CERT or other organisations. So changes take place immediately, especially which patches should be installed or which changes in the configuration should be made to avoid this vulnerability. Some of the files are transferred by FTP.

By the way: If we're not publishing well-known risks inheritant in any widely used platform or program that doesn't mean this particular platform or program is safe to use!

Chosen message with ID ae-200503-020

System: Several Anti-Virus Scanner Software
Topic: Filenames containing escape sequences archived in a ZIP file can lead to bypass AV scanning or unfiltered logging

ID: ae-200503-020

Anti-Virus-Scanner-Software, either local or as gateway scanner (SMTP or HTTP) decompresses archives to check their contents also.
Good decompression routines are smart enough to decompress files regardless the filename contain strange characters like escape sequences or not.
Also good AV software takes care about such escape sequences in case the decompressed filename would be logged.
Unfortunately, this is not always the case in current available software.
In our TXT-only available advisory more information about some affected products is available. Also, we provide some samples for testing this issue.
