CVSS v3.1
6.8
Medium
| Vector | AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
ISC BIND 9.x versions 9.9.8-P4 and earlier
ISC BIND 9.x versions 9.10.3-P4 and earlier
Description
The issue is related to the improper handling of DNAME records when parsing fetch reply messages, which allows remote attackers to cause a denial of service via a malformed packet to the rndc interface. This is related to errors in alist.c and sexpr.c. The vulnerability can be exploited by sending a specially crafted packet, leading to an assertion failure and daemon exit.
Recommendations
For ISC BIND 9.x versions 9.9.8-P4 and earlier, update to version 9.9.8-P4 or later.
For ISC BIND 9.x versions 9.10.3-P4 and earlier, update to version 9.10.3-P4 or later.
As a temporary workaround, consider restricting access to the rndc interface to minimize the risk of exploitation.
