Zusammenfassung:	The remote host is missing an update for the 'dhcp' package(s) announced via the MGASA-2021-0307 advisory.
Beschreibung:	Summary: The remote host is missing an update for the 'dhcp' package(s) announced via the MGASA-2021-0307 advisory. Vulnerability Insight: A flaw was found in the Dynamic Host Configuration Protocol (DHCP). There is a discrepancy between the code that handles encapsulated option information inleases transmitted 'on the wire' and the code which reads and parses lease information after it has been written to disk storage. This flaw allows an attacker to deliberately cause a situation where dhcpd while running in DHCPv4 or DHCPv6 mode, or the dhclient attempts to read a stored lease that contains option information, to trigger a stack-based buffer overflow in the option parsing code for colon-separated hex digits values. The highest threat from this vulnerability is to data confidentiality and integrity as well as service availability (CVE-2021-25217). Affected Software/OS: 'dhcp' package(s) on Mageia 7, Mageia 8. Solution: Please install the updated package(s). CVSS Score: 3.3 CVSS Vector: AV:A/AC:L/Au:N/C:N/I:N/A:P
