Microsoft Visual Studio time functions denial of service
| visualstudio-time-dos (32454) |  Low Risk |
Description:
Microsoft Visual Studio is vulnerable to a denial of service caused by an error in the Microsoft Visual C++ standard library time functions. By sending an overly long time_t argument, a remote attacker could exploit this vulnerability to cause an application using the Microsoft Visual C++ standard library time functions to crash.
Platforms Affected:
- Microsoft, Visual C++ 8.0
- Microsoft, Visual Studio 2005
Remedy:
No remedy available as of July 4, 2009.
Consequences:
Denial of Service

- CVE-2007-0842: The 64-bit versions of Microsoft Visual C++ 8.0 standard library (MSVCR80.DLL) time functions, including (1) localtime, (2) localtime_s, (3) gmtime, (4) gmtime_s, (5) ctime, (6) ctime_s, (7) wctime, (8) wctime_s, and (9) fstat, trigger an assertion error instead of a NULL pointer or EINVAL when processing a time argument later than Jan 1, 3000, which might allow context-dependent attackers to cause a denial of service (application exit) via large time values. NOTE: it could be argued that this is a design limitation of the functions, and the vulnerability lies with any application that does not validate arguments to these functions. However, this behavior is inconsistent with documentation, which does not list assertions as a possible result of an error condition.
