igmpproxy 0.4 before commit 2b30c36 allows remote attackers to cause a denial of service (application crash) via a crafted IGMPv3 membership report packet with a malicious source address. Due to insufficient validation in the `recv_igmp()` function in src/igmpproxy.c, an invalid group record type can trigger a NULL pointer dereference when logging the address using `inet_fmtsrc()`. This vulnerability can be exploited by sending malformed multicast traffic to a host running igmpproxy, leading to a crash. igmpproxy is used in various embedded networking environments and consumer-grade IoT devices (such as home routers and media gateways) to handle multicast traffic for IPTV and other streaming services. Affected devices that rely on unpatched versions of igmpproxy may be vulnerable to remote denial-of-service attacks across a LAN .

Unauthenticated heap buffer overflow in Gorrila codec decompression

ClickHouse is an open-source column-oriented database management system that allows generating analytical data reports in real-time. A heap buffer overflow issue was discovered in ClickHouse server. An attacker could send a specially crafted payload to the native interface exposed by default on port 9000/tcp, triggering a bug in the decompression logic of Gorilla codec that crashes the ClickHouse server process. This attack does not require authentication. This issue has been addressed in ClickHouse Cloud version 23.9.2.47551 and ClickHouse versions 23.10.5.20, 23.3.18.15, 23.8.8.20, and 23.9.6.20.

Junos OS: Upon receipt of specific sequences of genuine packets destined to the device the kernel will crash and restart (vmcore)

A buffer overflow vulnerability in the TCP/IP stack of Juniper Networks Junos OS allows an attacker to send specific sequences of packets to the device thereby causing a Denial of Service (DoS). By repeatedly sending these sequences of packets to the device, an attacker can sustain the Denial of Service (DoS) condition. The device will abnormally shut down as a result of these sent packets. A potential indicator of compromise will be the following message in the log files: "eventd[13955]: SYSTEM_ABNORMAL_SHUTDOWN: System abnormally shut down" These issue are only triggered by traffic destined to the device. Transit traffic will not trigger these issues. This issue affects: Juniper Networks Junos OS 12.3 versions prior to 12.3R12-S19; 15.1 versions prior to 15.1R7-S10; 16.1 version 16.1R1 and later versions; 16.2 version 16.2R1 and later versions; 17.1 version 17.1R1 and later versions; 17.2 version 17.2R1 and later versions; 17.3 versions prior to 17.3R3-S12; 17.4 version 17.4R1 and later versions; 18.1 versions prior to 18.1R3-S13; 18.2 version 18.2R1 and later versions; 18.3 versions prior to 18.3R3-S5; 18.4 versions prior to 18.4R2-S9, 18.4R3-S9; 19.1 versions prior to 19.1R3-S6; 19.2 versions prior to 19.2R1-S7, 19.2R3-S3; 19.3 versions prior to 19.3R2-S7, 19.3R3-S3; 19.4 versions prior to 19.4R3-S5; 20.1 versions prior to 20.1R2-S2, 20.1R3-S1; 20.2 versions prior to 20.2R3-S2; 20.3 versions prior to 20.3R3; 20.4 versions prior to 20.4R2-S1, 20.4R3; 21.1 versions prior to 21.1R1-S1, 21.1R2; 21.2 versions prior to 21.2R1-S1, 21.2R2.
