Title: MailScanner Attachment Filename Validation Vulnerability
Severity: HIGH
Description:
MailScanner is an e-mail security product. It is designed to be deployed on gateway systems and provides the ability to detect e-mail based attacks such as viruses. It will run on Unix and Linux variants and provides support for a number of anti-virus products.
A vulnerability has been reported in how MailScanner handles filenames for attachments. MailScanner does not sufficiently validate certain types of malformed filenames.
It may be possible to bypass MailScanner security with attachment filenames that contain excessive trailing/leading whitespace, are blank, or use character encodings that are unknown to MailScanner.
The exact consequences of this vulnerability are not known, but it is possible that some attachments with malicious filenames may slip through MailScanner or that a malformed filename may cause other aspects of MailScanner to fail.
