Title:	Debian: Security Advisory (DLA-2807-1)
Summary:	The remote host is missing an update for the Debian 'bind9' package(s) announced via the DLA-2807-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'bind9' package(s) announced via the DLA-2807-1 advisory. Vulnerability Insight: CVE-2021-25219 Kishore Kumar Kothapalli discovered that the lame server cache in BIND, a DNS server implementation, can be abused by an attacker to significantly degrade resolver performance, resulting in denial of service (large delays for responses for client queries and DNS timeouts on client hosts). CVE-2018-5740 'deny-answer-aliases' is a little-used feature intended to help recursive server operators protect end users against DNS rebinding attacks, a potential method of circumventing the security model used by client browsers. However, a defect in this feature makes it easy, when the feature is in use, to experience an assertion failure in name.c. For Debian 9 stretch, these problems have been fixed in version 1:9.10.3.dfsg.P4-12.3+deb9u10. We recommend that you upgrade your bind9 packages. For the detailed security status of bind9 please refer to its security tracker page at: [link moved to references] Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references] Affected Software/OS: 'bind9' package(s) on Debian 9. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
