Improper Restriction of Operations within the Bounds of a Memory Buffer

CVE-2007-5256

Severity High
Score 7.5/10

Summary

Multiple stack-based buffer overflows in FSD 2.052 d9 and earlier, and FSFDT FSD 3.000 d9 and earlier, allow (1) remote attackers to execute arbitrary code via a long HELP command on TCP port 3010 to the sysuser::exechelp function in sysuser.cc and (2) remote authenticated users to execute arbitrary code via long commands on TCP port 6809 to the servinterface::sendmulticast function in servinterface.cc, as demonstrated by a PIcallsign command.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
