CVE-2025-15683

Multiple Unauthenticated Denial-of-Service Conditions

TBEA TLogger V2.1.0.0B0.0.0.0 contains multiple unauthenticated denial-of-service vulnerabilities in its web server. An unauthenticated remote attacker can invoke specific HTTP endpoints to reboot or reset the device, clear application data, or terminate the web server through a segmentation fault. In addition, multiple action endpoints process attacker-controlled parameters using unsafe string operations such as sprintf() and strcat() without adequate bounds checking, allowing crafted input to trigger buffer overflows and crash the web server. The affected endpoints include onRestart, onReset, ClearData, uploadInvFile, getIndiaRPData, YearCaparity, TotalfaultData, recordData, InvHistoryData, CollectHistoryData, InvFaultData, GetPortTableByParm, and UpdatePortConfig.

CVE-2026-6791

Potential stack-based buffer clash during tilde expansion in wordexp

When expanding paths that begin with a tilde (~) followed by a username, the internal parse_tilde function extracts the username to determine the user's home directory. The implementation allocates memory for this username directly on the stack using the strndupa macro. Because the size of this allocation was determined by the length of the user-supplied input without any bounds checks, passing an excessively long username e.g. thousands of characters, forces the thread to exhaust its stack space. Thus if an application passes untrusted, attacker-controlled input to the wordexp function, an attacker can trigger a stack clash.

Cisco Adaptive Security Appliance Software and Firepower Threat Defense Software Web Services Denial of Service Vulnerability

A vulnerability in the web services interface of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition. This vulnerability is due to improper input validation when parsing HTTPS requests. An attacker could exploit this vulnerability by sending a malicious HTTPS request to an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

ClamAV GPT File Format Processing Memory Corruption Vulnerability

A vulnerability in the GPT file format parser of ClamAV could allow an unauthenticated, remote attacker to cause a DoS condition or possibly other expanded impacts as a result of&nbsp;memory corruption on an affected device. This vulnerability is due to improper handling of an endian conversion operation, which may result in an out-of-bounds buffer write. An attacker could exploit this vulnerability by submitting a crafted GPT file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to cause the ClamAV scanning process to terminate, resulting in a DoS condition on the affected software.
