Microsoft Windows Task Scheduler buffer overflow
| win-taskscheduler-bo (16591) |  High Risk |
Description:
Microsoft Windows could allow a remote attacker to execute code, caused by a buffer overflow in the Task Scheduler component. Task Scheduler saves tasks as files with .job file name extensions. By creating a specially-crafted .job file containing malicious script, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the victim, once the file is opened. An attacker could exploit this vulnerability by hosting the malicious file on a Web site or by sending it to a victim as an HTML email. The attacker could also add a .job file to a local file system or a network share and persuade the victim to view the folder using Windows Explorer or use a program that passes parameters to the vulnerable parameter to exploit this vulnerability.
Platforms Affected:
- Microsoft, Internet Explorer 6
- Microsoft, Windows 2000 SP2
- Microsoft, Windows 2000 SP3
- Microsoft, Windows 2000 SP4
- Microsoft, Windows XP SP1
- Microsoft, Windows XP SP1 64-bit
Remedy:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS04-022. See References.
Consequences:
Gain Access
