The remote host is running Bind, a popular name server.
Versions of BIND 9.6-ESV earlier than 9.6-ESV-R7-P2, 9.7.x earlier than 9.7.6-P2, 9.8.x earlier than 9.8.3-P2, and than 9.9.1-P2 are potentially affected by the following vulnerabilities :
Under a heavy query load, the application may use uninitialized data structures related to failed query cache access. This error can cause the application to crash. Note this issue only affects the application when DNSSEC validation is enabled. (CVE-2012-3817)
Under a heavy, incoming TCP query load, the application can be affected by a memory leak that can lead to decreased performance and application termination on systems that kill processes that are out of memory. (CVE-2012-3868)
