Título:	Mageia: Security Advisory (MGASA-2022-0374)
Resumen:	The remote host is missing an update for the 'dhcp' package(s) announced via the MGASA-2022-0374 advisory.
Descripción:	Summary: The remote host is missing an update for the 'dhcp' package(s) announced via the MGASA-2022-0374 advisory. Vulnerability Insight: In ISC DHCP 4.4.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1, when the function option_code_hash_lookup() is called from add_option(), it increases the option's refcount field. However, there is not a corresponding call to option_dereference() to decrement the refcount field. The function add_option() is only used in server responses to lease query packets. Each lease query response calls this function for several options, so eventually, the reference counters could overflow and cause the server to abort. (CVE-2022-2928) In ISC DHCP 1.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1 a system with access to a DHCP server, sending DHCP packets crafted to include fqdn labels longer than 63 bytes, could eventually cause the server to run out of memory. (CVE-2022-2929) Affected Software/OS: 'dhcp' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 6.1 CVSS Vector: AV:A/AC:L/Au:N/C:N/I:N/A:C
