CVE-2017-3141

Summary

The BIND installer on Windows uses an unquoted service path which can enable a local user to achieve privilege escalation if the host file system permissions allow this. Affects BIND 9.2.6-P2->9.2.9, 9.3.2-P1->9.3.6, 9.4.0->9.8.8, 9.9.0->9.9.10, 9.10.0->9.10.5, 9.11.0->9.11.1, 9.9.3-S1->9.9.10-S1, 9.10.5-S1.

Affected Software

Weaknesses

• This vulnerability exists in the installer delivered with BIND for Windows and not within BIND itself. Non-Windows builds and installations are unaffected. A manual installation of BIND where the service path is quoted when added would not be at risk.

Workarounds

BIND installations on Windows are not at risk if the host file permissions prevent creation of a binary in a location where the service executor would run it instead of named.exe.
