Title:	ISC BIND DoS Vulnerability (CVE-2023-5517) - Linux
Summary:	ISC BIND is prone to a denial of service (DoS) vulnerability.
Description:	Summary: ISC BIND is prone to a denial of service (DoS) vulnerability. Vulnerability Insight: A flaw in query-handling code can cause named to exit prematurely with an assertion failure when: - nxdomain-redirect is configured, and - the resolver receives a PTR query for an RFC 1918 address that would normally result in an authoritative NXDOMAIN response. Vulnerability Impact: If both of the above conditions are met, a single suitable query will cause named to crash. Affected Software/OS: ISC BIND version 9.12.0 through 9.16.45, 9.18.0 through 9.18.21, 9.19.0 through 9.19.19, 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
