Internet Security Systems Protection Brief
February 10, 2005

F-Secure AntiVirus Library Heap Overflow

Summary:

ISS has shipped protection for a flaw X-Force has discovered in F-Secure
AntiVirus Library. The F-Secure AntiVirus Library is widely relied upon
to provide antivirus capabilities to desktop, server, and gateway systems.
Also, several large vendors and ISP's implement F-Secure's AntiVirus
Library in their products. By crafting a archive file, an attacker is able
to trigger a heap overflow within the process importing the F-Secure
AntiVirus Library.

Business Impact:

Compromise of antivirus protected networks and machines may lead to
exposure of confidential information, loss of productivity, and further
network compromise. Successful exploitation of this vulnerability could
be used to gain unauthorized access to networks and machines being
protected by F-Secure AntiVirus Library product. Implementations of
F-Secure AntiVirus Library are likely vulnerable through common
protocols, e.g. SMTP, HTTP, FTP. No authentication is required for an
attacker to leverage this vulnerability to compromise a antivirus
protected network or machine. It is likely F-Secure AntiVirus Library
implementations are vulnerable in their default configurations.
