McAfee AntiVirus Library Stack Overflow

Summary:

ISS has shipped protection for a flaw X-Force has discovered in McAfee
AntiVirus Library versions prior to 4400. The McAfee AntiVirus Library
is widely relied upon to provide antivirus capabilities to desktop,
server, and gateway systems. Also, several large vendors and ISP's
implement McAfee's AntiVirus Library in their products. By crafting an
LHA file, an attacker is able to trigger a stack overflow within the
process importing the McAfee 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 McAfee
AntiVirus Library product. Implementations of McAfee AntiVirus Library are
likely vulnerable through common protocols, e.g. SMTP, HTTP, FTP, SMB. No
authentication is required for an attacker to leverage this vulnerability
to compromise a antivirus protected network or machine. It is likely McAfee
AntiVirus Library implementations are vulnerable in their default
configurations.
