Title:	Mageia: Security Advisory (MGASA-2023-0303)
Summary:	The remote host is missing an update for the 'bind' package(s) announced via the MGASA-2023-0303 advisory.
Description:	Summary: The remote host is missing an update for the 'bind' package(s) announced via the MGASA-2023-0303 advisory. Vulnerability Insight: The code that processes control channel messages sent to `named` calls certain functions recursively during packet parsing. Recursion depth is only limited by the maximum accepted packet size, depending on the environment, this may cause the packet-parsing code to run out of available stack memory, causing `named` to terminate unexpectedly. Since each incoming control channel message is fully parsed before its contents are authenticated, exploiting this flaw does not require the attacker to hold a valid RNDC key, only network access to the control channel's configured TCP port is necessary. (CVE-2023-3341) A flaw in the networking code handling DNS-over-TLS queries may cause `named` to terminate unexpectedly due to an assertion failure. This happens when internal data structures are incorrectly reused under significant DNS-over-TLS query load. (CVE-2023-4236) Affected Software/OS: 'bind' package(s) on Mageia 9. Solution: Please install the updated package(s). CVSS Score: 7.8 CVSS Vector: AV:N/AC:L/Au:N/C:N/I:N/A:C
