GEN:SID 1:2487
Message SMTP WinZip MIME content-type buffer overflow
Summary This event is generated when an attempt is made to exploit a buffer overflow
associated with winzip's processing of certain MIME archive files.
Impact A successful attack may permit a buffer overflow that allows the execution
of arbitrary code at the privilege level of the user running winzip.
Detailed Information Winzip is a program that is used for file compression on Windows hosts.
A buffer overflow exists when parsing specific header fields for certain
MIME file types.  An overly long value passed to specific Content-Type attributes
may trigger the buffer overflow and allow the execution of arbitrary code
in the context of the user running winzip.
Affected Systems Winzip 6.x, 7.x, 8.0, 8.1 SR-1, 8.1, Winzip 9.0 beta versions
Attack Scenarios An attacker can entice a user to open a malformed MIME file that will
invoke winzip to process it, possibly causing a a buffer overflow
and the subsequent execution of arbitrary code on the vulnerable host.
Ease of Attack Simple.
Corrective Action Upgrade to the latest non-affected version of the software.
