| Detailed Description |
According to its self-reported version number, the remote installation of BIND is affected by multiple 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)
* Note: This check solely relied on the banner of the remote DNS server to assess this vulnerability, so this might be a false positive.
