Patch Published: 2008-06-25
CVE [?]: CVE-2008-2499
CPE [?]: cpe:/a:ibm:lotus_sametime

Synopsis

The remote server hosts an application that contains a buffer overflow vulnerability.

Description

The version of Lotus Sametime STMux.exe on the remote host is prone to a remote stack-based buffer overflow attack because it fails to properly bounds-check user-supplied data before copying it to an insufficiently sized memory buffer.
