Alt-N MDaemon POP3 Server USER And APOP Commands Buffer Overflow
Publish date: February 10, 2011
Severity: MEDIUM
CVE Identifier: CVE-2006-4364
Advisory Date: FEB 10, 2011
DESCRIPTION
Alt-N MDaemon POP3 Server is susceptible to multiple remote buffer-overflow vulnerabilities. The issues are due to the application's failure to properly bounds-check user-supplied input before copying it to insufficiently sized memory buffers. These issues allow remote, unauthenticated attackers to execute arbitrary machine code in the context of affected servers. This may facilitate the compromise of affected computers. MDaemon versions 8 and 9 are reported to be vulnerable; previous versions may be affected as well.
TREND MICRO PROTECTION INFORMATION
Trend Micro Deep Security shields networks through Deep Packet Inspection (DPI) rules. Trend Micro customers using OfficeScan with Intrusion Defense Firewall (IDF) plugin are also protected from attacks using these vulnerabilities. Please refer to the filter number and filter name when applying appropriate DPI and/or IDF rules.
