CVE-2015-5477 is a relatively easily expoitable denial-of-service (DoS) vector against authorative AND recursive BIND server.
Because the code defect occurs quite early in packet processing (before decision points concerning access control lists or limitations on authorative or recursive services are applied) it is infeasible to block via server configuration.
Deployment of patched versions is the recommended solution.
All versions of BIND 9 and BIND 9.1.0 (inclusive) through BIND 9.9.7-P1 and BIND 9.10.2-P2 are vulnerable.
Patches for SLES 11 SP1 (LTSS) and SLES 10 SP4 have been released on the 30th of July.
Systems needs to be patched to the following BIND versions:
- SLES 12:
- SLES 11:
- SLES 11 SP1 (LTSS): bind-9.6ESVR11W1-0.4.1
- SLES 11 SP2 (LTSS): bind-9.9.6P1-0.10.1
- SLES 11 SP3: bind-9.9.6P1-0.10.1
- SLES 11 SP4: bind-9.9.6P1-0.10.1
- SLES 10:
- SLES 10 SP4 (LTSS): bind-9,6ESVR11P1-0.12.1
