Nixu Information for VU#738331
Domain Name System (DNS) resolver libraries vulnerable to read buffer overflow
Nixu NameSurfer itself does not contain any parts of the resolver library being discussed, nor does it call the res_* functions directly. However, parts of NameSurfer are dynamically linked with the resolver library on the DNS server machine. Therefore, if the underlying system is vulnerable, the vulnerability propagates also to NameSurfer.
Nixu recommends that the resolver on the DNS server running NameSurfer is upgraded according to ISC's advisory as published by CERT. No further actions are required.
