- While this bug has existed in BIND since 9.0.0, there are no known code paths leading to it in ISC releases prior to those containing the fix for CVE-2017-3137. Thus while all instances of BIND ought to be patched, only ISC versions [9.9.9-P8 to 9.9.11, 9.10.4-P8 to 9.10.6, 9.11.0-P5 to 9.11.2, 9.9.9-S10 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, and 9.12.0a1 to 9.12.0rc1] acting as DNSSEC validating resolvers are currently known to crash due to this bug. The known crash is an assertion failure in netaddr.c.
Summary
BIND was improperly sequencing cleanup operations on upstream recursion fetch contexts, leading in some cases to a use-after-free error that can trigger an assertion failure and crash in named. Affects BIND 9.0.0 to 9.8.x, 9.9.0 to 9.9.11, 9.10.0 to 9.10.6, 9.11.0 to 9.11.2, 9.9.3-S1 to 9.9.11-S1, 9.10.5-S1 to 9.10.6-S1, 9.12.0a1 to 9.12.0rc1.
