| Título: | ISC BIND DoS Vulnerability (CVE-2023-4408) - Linux |
| Resumen: | ISC BIND is prone to a denial of service (DoS) vulnerability. |
| Descripción: | Summary: ISC BIND is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: The DNS message parsing code in named includes a section whose computational complexity is overly high. It does not cause problems for typical DNS traffic, but crafted queries and responses may cause excessive CPU load on the affected named instance by exploiting this flaw. This issue affects both authoritative servers and recursive resolvers. Vulnerability Impact: By flooding the target server with queries exploiting this flaw an attacker can significantly impair the server's performance, effectively denying legitimate clients access to the DNS resolution service. Affected Software/OS: ISC BIND version 9.0.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 9.9.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.45-S1 and 9.18.11-S1 through 9.18.21-S1. Solution: Update to version 9.16.48, 9.18.24, 9.19.21, 9.16.48-S1, 9.18.24-S1 or later. CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C |
