Notes for BIND 9.16.48
|
|
----------------------
|
|
|
|
Security Fixes
|
|
~~~~~~~~~~~~~~
|
|
|
|
- Validating DNS messages containing a lot of DNSSEC signatures could
|
|
cause excessive CPU load, leading to a denial-of-service condition.
|
|
This has been fixed. :cve:`2023-50387`
|
|
|
|
ISC would like to thank Elias Heftrig, Haya Schulmann, Niklas Vogel,
|
|
and Michael Waidner from the German National Research Center for
|
|
Applied Cybersecurity ATHENE for bringing this vulnerability to our
|
|
attention. :gl:`#4424`
|
|
|
|
- Preparing an NSEC3 closest encloser proof could cause excessive CPU
|
|
load, leading to a denial-of-service condition. This has been fixed.
|
|
:cve:`2023-50868` :gl:`#4459`
|
|
|
|
- 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 ``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`
|
|
|
|
- Query patterns that continuously triggered cache database maintenance
|
|
could cause an excessive amount of memory to be allocated, exceeding
|
|
``max-cache-size`` and potentially leading to all available memory on
|
|
the host running :iscman:`named` being exhausted. This has been fixed.
|
|
:cve:`2023-6516`
|
|
|
|
ISC would like to thank Infoblox for bringing this vulnerability to
|
|
our attention. :gl:`#4383`
|
|
|
|
Removed Features
|
|
~~~~~~~~~~~~~~~~
|
|
|
|
- Support for using AES as the DNS COOKIE algorithm (``cookie-algorithm
|
|
aes;``) has been deprecated and will be removed in a future release.
|
|
Please use the current default, SipHash-2-4, instead. :gl:`#4421`
|
|
