Microsoft Data Access Components (MDAC) broadcast request buffer overflow
|mdac-broadcastrequest-bo (14187)||High Risk|
Microsoft Data Access Components (MDAC) is vulnerable to a buffer overflow, caused by improper bounds checking in a specific MDAC component. If a remote attacker spoofs a SQL server that listens on a network for a vulnerable system to send a broadcast request, the attacker could then send a specially-crafted UDP packet in response to a request to overflow a buffer and execute code on the system with privileges of the process executing MDAC.
Note: This vulnerability is similar to the vulnerability previously discussed in Microsoft Security Bulletin MS03-033. However, the vulnerable codepath for this vulnerability is different from the vulnerable codepath of the vulnerability reported in Microsoft Security Bulletin MS03-033.
Apply the patch for this vulnerability, as listed in Microsoft Security Bulletin MS04-003. See References.
