- 漏洞讨论

A remote buffer overflow vulnerability affects BIND. This issue is due to a failure of the application to properly validate the length of user-supplied input prior to copying it into static process buffers.

An attacker may leverage this issue to trigger a denial of service condition. It should be noted that this issue may also facilitate code execution with the privileges of the affected utility, however this is not confirmed.
