Advisory from Moritz Jodeit, November 8th, 2008 :

ClamAV contains an off-by-one heap overflow vulnerability in the code responsible for parsing VBA project files. Successful exploitation could allow an attacker to execute arbitrary code with the privileges of the `clamd' process by sending an email with a prepared attachment.

A VBA project file embedded inside an OLE2 office document send as an attachment can trigger the off-by-one.

Entry from Thu Oct 30 13:52:42 CET 2008 (acab) in ChangeLog :

libclamav/vba_extract.c: get_unicode_name off-by-one, bb#1239 reported by Moritz Jodeit >moritz*<
