ISC BIND 9 Multiple Denial of Service Vulnerabilities
High Nessus Plugin ID 60120
The remote name server may be affected by multiple denial of service vulnerabilities.
According to its self-reported version number, the remote installation of BIND is affected by multiple denial of service 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 that Nessus has only relied on the version itself and has not attempted to determine whether or not the install is actually affected.
Upgrade to BIND 9.6-ESV-R7-P2 / 9.7.6-P2 / 9.8.3-P2 / 9.9.1-P2 or later.
