An issue was discovered on Alecto IVM-100 2019-11-12 devices. The device uses a custom UDP protocol to start and control video and audio services. The protocol has been partially reverse engineered. Based upon the reverse engineering, no password or username is ever transferred over this protocol. Thus, one can set up the camera connection feed with only the encoded UID. It is possible to set up sessions with the camera over the Internet by using the encoded UID and the custom UDP protocol, because authentication happens at the client side.
30be5b3d8a4c41b0bd80dbb9c3ff49c1407c5db44ff864668aaab8728b0c851dUbuntu Security Notice 6885-2 - USN-6885-1 fixed vulnerabilities in Apache HTTP Server. One of the security fixes introduced a regression when proxying requests to a HTTP/2 server. This update fixes the problem. Marc Stern discovered that the Apache HTTP Server incorrectly handled serving WebSocket protocol upgrades over HTTP/2 connections. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. Orange Tsai discovered that the Apache HTTP Server mod_proxy module incorrectly sent certain request URLs with incorrect encodings to backends. A remote attacker could possibly use this issue to bypass authentication. Orange Tsai discovered that the Apache HTTP Server mod_rewrite module incorrectly handled certain substitutions. A remote attacker could possibly use this issue to execute scripts in directories not directly reachable by any URL, or cause a denial of service. Some environments may require using the new UnsafeAllow3F flag to handle unsafe substitutions. Orange Tsai discovered that the Apache HTTP Server incorrectly handled certain response headers. A remote attacker could possibly use this issue to obtain sensitive information, execute local scripts, or perform SSRF attacks. Orange Tsai discovered that the Apache HTTP Server mod_proxy module incorrectly handled certain requests. A remote attacker could possibly use this issue to cause the server to crash, resulting in a denial of service. It was discovered that the Apache HTTP Server incorrectly handled certain handlers configured via AddType. A remote attacker could possibly use this issue to obtain source code.

2e1588aae53cb32d43937f1f4eca28febd9c0c7aa1734fc5dd61a7e81e0ebcddDebian Linux Security Advisory 5724-1 - The Qualys Threat Research Unit (TRU) discovered that OpenSSH, an implementation of the SSH protocol suite, is prone to a signal handler race condition. If a client does not authenticate within LoginGraceTime seconds (120 by default), then sshd's SIGALRM handler is called asynchronously and calls various functions that are not async-signal-safe. A remote unauthenticated attacker can take advantage of this flaw to execute arbitrary code with root privileges. This flaw affects sshd in its default configuration.

This update provides the corresponding updates for Ubuntu 24.04 LTS. Dan Fandrich discovered that curl would incorrectly use the default set of protocols when a parameter option disabled all protocols without adding any, contrary to expectations. This issue only affected Ubuntu 23.10. It was discovered that curl incorrectly handled memory when limiting the amount of headers when HTTP/2 server push is allowed. A remote attacker could possibly use this issue to cause curl to consume resources, leading to a denial of service.

186243d4c27faa63ab8d52c327cc0396d841121b76a1d45b444edac2801ebb9aNmap is a utility for port scanning large networks, although it works fine for single hosts. Sometimes you need speed, other times you may need stealth. In some cases, bypassing firewalls may be required. Not to mention the fact that you may want to scan different protocols (UDP, TCP, ICMP, etc.). Nmap supports Vanilla TCP connect() scanning, TCP SYN (half open) scanning, TCP FIN, Xmas, or NULL (stealth) scanning, TCP ftp proxy (bounce attack) scanning, SYN/FIN scanning using IP fragments (bypasses some packet filters), TCP ACK and Window scanning, UDP raw ICMP port unreachable scanning, ICMP scanning (ping-sweep), TCP Ping scanning, Direct (non portmapper) RPC scanning, Remote OS Identification by TCP/IP Fingerprinting, and Reverse-ident scanning. Nmap also supports a number of performance and reliability features such as dynamic delay time calculations, packet timeout and retransmission, parallel port scanning, detection of down hosts via parallel pings.
