CVE-2022-2929 – DHCP memory leak
https://notcve.org/view.php?id=CVE-2022-2929
06 Oct 2022 — 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. En ISC DHCP versiones 1.0 anteriores a 4.4.3, ISC DHCP versiones 4.1-ESV-R1 anteriores a 4.1-ESV-R16-P1, un sistema con acceso a un servidor DHCP, enviando paquetes DHCP diseñados para incluir etiquetas fqdn de más de 63 bytes, podría llegar a causar a el servidor quedarse sin m... • https://kb.isc.org/docs/cve-2022-2929 • CWE-770: Allocation of Resources Without Limits or Throttling •
