MS11-058: Vulnerabilities in DNS Server Could Allow Remote Code Execution (2562485) (remote check)

Critical Nessus Plugin ID 55883


The DNS server running on the remote host is affected by a memory corruption vulnerability.


The version of Windows DNS server running on the remote host has a memory corruption vulnerability that can be triggered by making a specially crafted NAPTR query. This could allow an attacker to write arbitrary data to the heap and potentially execute arbitrary code.

Note that upstream servers may filter this request, creating a false negative, or may be vulnerable themselves, creating a false positive.
If the target is patched and shows up as vulnerable, check your upstream DNS servers.

Note also that while Microsoft's advisory referenced multiple vulnerabilities, Nessus only tests for the vulnerability described above.


Microsoft has released a set of patches for Windows 2003, 2008, and 2008 R2.
