Notes for BIND 9.18.22
|
|
----------------------
|
|
|
|
Security Fixes
|
|
~~~~~~~~~~~~~~
|
|
|
|
- Parsing DNS messages with many different names could cause excessive
|
|
CPU load. This has been fixed. :cve:`2023-4408`
|
|
|
|
ISC would like to thank Shoham Danino from Reichman University, Anat
|
|
Bremler-Barr from Tel-Aviv University, Yehuda Afek from Tel-Aviv
|
|
University, and Yuval Shavitt from Tel-Aviv University for bringing
|
|
this vulnerability to our attention. :gl:`#4234`
|
|
|
|
- Specific queries could cause :iscman:`named` to crash with an
|
|
assertion failure when :any:`nxdomain-redirect` was enabled. This has
|
|
been fixed. :cve:`2023-5517` :gl:`#4281`
|
|
|
|
- A bad interaction between DNS64 and serve-stale could cause
|
|
:iscman:`named` to crash with an assertion failure, when both of these
|
|
features were enabled. This has been fixed. :cve:`2023-5679`
|
|
:gl:`#4334`
|
|
|
|
Bug Fixes
|
|
~~~~~~~~~
|
|
|
|
- The counters exported via the statistics channel were changed back to
|
|
64-bit signed values; they were being inadvertently truncated to
|
|
unsigned 32-bit values since BIND 9.15.0. :gl:`#4467`
|
|
|
|
