FreeBSD : clamav -- off-by-one heap overflow in VBA project parser (24b64fb0-af1d-11dd-8a16-001b1116b350)
High Nessus Plugin ID 34728
SynopsisThe remote FreeBSD host is missing one or more security-related updates.
DescriptionAdvisory 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.
