Descripción técnica

GStreamer qtdemux Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the parsing of UncompressedFrameConfigBox structures. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29392.

———Autel MaxiCharger AC Elite Home NFC Stack-based Buffer Overflow Arbitrary Code Execution Vulnerability. This vulnerability allows physically present attackers to execute arbitrary code on affected installations of Autel MaxiCharger AC Elite Home EV chargers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of card responses via the NFC interface. A crafted card response can trigger an overflow of a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device.

———The TL-WR940N v6 router contains a vulnerability in its RTSP connection tracking module that can lead to a stack-based buffer overflow. The issue occurs when a LAN client initiates a connection to a malicious RTSP server controlled by an attacker. A specially crafted RTSP message may trigger improper memory handling within the kernel module Successful exploitation of this vulnerability may result in a denial-of-service (DoS) condition or allow remote code execution (RCE), potentially leading to full compromise of the device. This vulnerability can be exploited by an unauthenticated attacker under the device's default configuration.11h CVE-2026-671928.1 ALT

———Xlight FTP Server before 3.9.5 contains a pre-authentication stack buffer overflow vulnerability that allows unauthenticated attackers to corrupt stack memory by sending malformed SSH packets when a GCM cipher is negotiated. Attackers can craft packets with an unvalidated length field passed directly to the GCM decrypt function, overwriting the stack cookie and return address to potentially achieve remote code execution before any authentication occurs.10h CVE-2026-581817.5 ALT
