There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp relay docker to shutdown. Discovered by Eugene Lim of GovTech Singapore.

New upstream release: A security release. This release includes fix for CVE-2022-45059 (VSV00011) and CVE-2022-45060 (VSV00010). From the upstream release notes:
VSV00010 Varnish Request Smuggling Vulnerability
Date: 2022-11-08
A request smuggling attack can be performed on Varnish Cache servers by requesting that certain headers are made hop-by-hop, preventing the Varnish Cache servers from forwarding critical headers to the backend. Among the headers that can be filtered this way are both Content-Length and Host, making it possible for an attacker to both break the HTTP/1 protocol framing, and bypass request to host routing in VCL.
VSV00011 Varnish HTTP/2 Request Forgery Vulnerability
Date: 2022-11-08
A request forgery attack can be performed on Varnish Cache servers that have the HTTP/2 protocol turned on. An attacker may introduce characters through the HTTP/2 pseudo-headers that are invalid in the context of an HTTP/1 request line, causing the Varnish server to produce invalid HTTP/1 requests to the backend. This may in turn be used to successfully exploit vulnerabilities in a server behind the Varnish server.
CVE-2021-38827
Xiongmai Camera XM-JPR2-LX V4.02.R12.A6420987.10002.147502.00000 is vulnerable to account takeover.
CVE-2021-38828
Xiongmai Camera XM-JPR2-LX V4.02.R12.A6420987.10002.147502.00000 is vulnerable to plain-text traffic sniffing.
