These ISS products can be key components of a program for detecting network attacks and intrusions. PLATFORM: RealSecure Network 7.0, XPU 20.15 through 22.9 Real Secure Server Sensor 7.0 XPU 20.16 through 22.9 Proventia A Series XPU 20.15 through 22.9 Proventia G Series XPU 22.3 through 22.9 Proventia M Series XPU 1.3 through 1.7 RealSecure Desktop 7.0 eba through ebh RealSecure Desktop 3.6 ebr through ecb RealSecure Guard 3.6 ebr through ecb RealSecure Sentry 3.6 ebr through ecb BlackICE PC Protection 3.6 cbr through ccb BlackICE Server Protection 3.6 cbr through ccb DAMAGE: The heap overflow can potentially be used to execute arbitrary code. SOLUTION: Vendor recommends upgrading the software. ______________________________________________________________________________ VULNERABILITY The risk is HIGH. Externally facing networks Assessment that do ASSESSMENT: not allow remote SMB connections are not vulnerable to remote attacks. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/o-085.shtml ORIGINAL BULLETIN: http://xforce.iss.net/xforce/alerts/id/165 CVE/CAN: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= ______________________________________________________________________________ Visit ISS X-Force web site for their publication of this information. http://xforce.iss.net/xforce/alerts/id/165 _______________________________________________________________________________ CIAC wishes to acknowledge the contributions of xforce for the information contained in this bulletin. _______________________________________________________________________________ CIAC, the Computer Incident Advisory Capability, is the computer security incident response team for the U.S. Department of Energy (DOE) and the emergency backup response team for the National Institutes of Health (NIH).
