Two High-Severity Flaws in BIND Fixed

In a related development, ISC has released fixes for two high-severity bugs affecting the Berkeley Internet Name Domain (BIND) 9 Domain Name System (DNS) software suite that could pave the way for a DoS condition –

• CVE-2023-3341 (CVSS score: 7.5) – A stack exhaustion flaw in control channel code may cause named to terminate unexpectedly (fixed in versions 9.16.44, 9.18.19, 9.19.17, 9.16.44-S1, and 9.18.19-S1)
• CVE-2023-4236 (CVSS score: 7.5) – The named service may terminate unexpectedly under high DNS-over-TLS query load (fixed in versions 9.18.19 and 9.18.19-S1)

The latest patches arrive three months after ISC rolled out fixes for three other flaws in the software (CVE-2023-2828, CVE-2023-2829, and CVE-2023-2911, CVSS scores: 7.5) that could result in a DoS condition.
