Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity Medium
Score 6.4/10


Stack-based buffer overflow in the _lib_spawn_user_getpid function in (1) swatch.exe and (2) surgemail.exe in NetWin SurgeMail 38k4 and earlier, and beta 39a, allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via an HTTP request with multiple long headers to webmail.exe and unspecified other CGI executables, which triggers an overflow when assigning values to environment variables. NOTE: some of these details are obtained from third party information.

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.
