Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

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 .Show less

Capstone is a disassembly framework. In versions 6.0.0-Alpha5 and prior, an unchecked vsnprintf return in SStream_concat lets a malicious cs_opt_mem.vsnprintf drive SStream’s index negative or past the end, leading to a stack buffer underflow/overflow when the next write occurs. Commit 2c7797182a1618be12017d7d41e0b6581d5d529e fixes the issue.Show less

RIOT is an open-source microcontroller operating system, designed to match the requirements of Internet of Things (IoT) devices and other embedded devices. A vulnerability was discovered in the IPv6 fragmentation reassembly implementation of RIOT OS v2025.07. When copying the contents of the first fragment (offset=0) into the reassembly buffer, no size check is performed. It is possible to force the creation of a small reassembly buffer by first sending a shorter fragment (also with offset=0). Overflowing the reassembly buffer corrupts the state of other packet buffers which an attacker might be able to used to achieve further memory corruption (potentially resulting in remote code execution). To trigger the vulnerability, the `gnrc_ipv6_ext_frag` module must be included and the attacker must be able to send arbitrary IPv6 packets to the victim. Version 2025.10 fixes the issue.Show less

A buffer overflow issue was addressed with improved memory handling. This issue is fixed in Safari 26.2, iOS 18.7.3 and iPadOS 18.7.3, iOS 26.2 and iPadOS 26.2, macOS Tahoe 26.2, visionOS 26.2. Processing maliciously crafted web content may lead to an unexpected process crash.Show less

A Buffer overflow vulnerability in function fromAdvSetMacMtuWan of bin httpd in Tenda AC10V4.0 V16.03.10.20 allows remote attackers to cause denial of service and possibly code execution by sending a post request with a crafted payload (field `serverName`) to /goform/AdvSetMacMtuWan.Show less

Meltytech Shotcut 25.10.31 is vulnerable to Buffer Overflow. A memory access violation occurs when processing MLT project files with manipulated width and height parameters. By setting these values to extremely large numbers, the application attempts to allocate excessive memory during image processing, triggering a buffer overflow in the mlt_image_fill_white function.Show less

NanoMQ is a messaging broker/bus for IoT Edge & SDV. Versions prior to 0.24.4 have a buffer overflow case while the PUBLISH packets trigger both shared subscription and vanila subscription. This is fixed in version 0.24.4. As a workaround, disable shared subscription.Show less

GOM Player 2.3.90.5360 contains a buffer overflow vulnerability in the equalizer preset name input field that allows attackers to crash the application. Attackers can overwrite the preset name with 260 'A' characters to trigger a buffer overflow and cause application instability.Show less

A security vulnerability has been detected in Shiguangwu sgwbox N3 2.0.25. Affected by this issue is some unknown functionality of the file /usr/sbin/http_eshell_server of the component WIRELESSCFGGET Interface. The manipulation of the argument params leads to buffer overflow. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.Show less
