CVE-2026-71267 1 Rxi 1 Microtar 2026-08-10 9.8 Critical
microtar's mtar_write_file_header and mtar_write_dir_header functions (src/microtar.c) copy a caller-supplied entry name into the 100-byte field of a stack-allocated mtar_header_t via strcpy(h.name, name), with no check that strlen(name) is less than 100 before the copy.
CVE-2026-71266 1 Syoyo 1 Tinyobjloader-c 2026-08-10 7.8 High
tinyobjloader-c's tinyobj_parse_and_index_mtl_file (tinyobj_loader_c.h) reads each line of a .mtl material file into a fixed 4096-byte stack buffer via memcpy(linebuf, p, p_len), guarded only by . The identical vulnerable pattern is duplicated in a second function in the same file.
CVE-2026-71265 1 Domoticz 1 Domoticz 2026-08-10 7.5 High
Domoticz's MochadTCP::MatchLine handler for MOCHAD_RFSEC messages (hardware/MochadTCP.cpp) copies network-received data from the up-to-1028-byte m_mochadbuffer into a fixed 50-byte stack buffer tempRFSECbuf using strcpy with no length check, across three separate code branches (DS10A/KR10A/MS10A device types).
CVE-2026-55738 1 Rxi 1 Microtar 2026-08-10 8.8 High
A stack-based buffer overflow exists in the raw_to_header function in src/microtar.c in rxi microtar 0.1.0. The function copies the 100-byte name and linkname fields of a TAR header with strcpy without guaranteeing null termination of the source.
CVE-2026-20345 1 Cisco 1 Secure Endpoint 2026-08-08 7.5 High
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 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.

CVE-2026-18909 1 Elan Microelectronics Corp. 1 Elan Smart-pad 2026-08-07 4.7 Medium
A stack-based buffer overflow vulnerability exists in ELAN Microelectronics Corp. ELAN Smart-Pad on Windows (ETD.sys and ETDSMBus.sys). During Intel SMBus recovery, ETDSMBus.sys does not enforce an upper-bound check on the hardware-derived report count, allowing an out-of-range value to be forwarded to ETD.sys where it is used as a loop counter for a stack buffer copy without destination size validation. A local attacker with standard user privileges can trigger a kernel bugcheck (BSOD 0xF7 DRIVER_OVERRAN_STACK_BUFFER), resulting in denial of service. This issue affects ELAN Smart-Pad through ETD24.21.52.3.
CVE-2020-37121 1 Codeblocks 2 Code::blocks, Code\\ 2026-08-06 5.5 Medium
CODE::BLOCKS 16.01 contains a buffer overflow vulnerability that allows attackers to execute arbitrary code by overwriting Structured Exception Handler with crafted Unicode characters. Attackers can create a malicious text file with 1982 bytes of buffer and shellcode to trigger remote code execution.
CVE-2026-67866 1 Systerel 1 S2opc 2026-08-06 7.5 High
Buffer Overflow vulnerability in Systerel S2OPC 1.7.3 allows a remote attacker to cause a denial of service via the LockedStaMac_ProcessMsg_DeleteMonitoredItemsResponse and SOPC_StaMac_NewDeleteMonitoredItems in the client wrapper DeleteMonitoredItems path
CVE-2026-55980 1 Secureage 1 Catchpulse 2026-08-06 5.5 Medium
A denial-of-service vulnerability in CatchPulse could allow an attacker to conduct a stack buffer overrun attack, leading to a denial-of-service condition.
CVE-2026-67673 2026-08-05 4.6 Medium
A stack-based buffer overflow vulnerability exists in the cmd_edl function of OreSat Firmware v1.0. The vulnerability is triggered when processing the edl fw_flash command, where the <filename> argument is copied to a 64-byte stack buffer via memcpy without proper length validation. An attacker with physical access to the UART3 serial interface can exploit this vulnerability by sending a maliciously crafted command with an oversized filename parameter,
CVE-2026-18898 1 Utt 1 Hiper 1200gw 2026-08-05 8.8 High
A security flaw has been discovered in UTT HiPER 1200GW up to v2.5.3-170306. This affects the function strcpy of the file /goform/ConfigAdvideo. The manipulation of the argument timestart results in stack-based buffer overflow. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-18897 1 Utt 1 Hiper 1250gw 2026-08-05 8.8 High
A vulnerability was identified in UTT HiPER 1250GW up to v3.2.7-210907-180535. The impacted element is the function strcpy of the file /goform/getOneApConfTempEntry. The manipulation of the argument tempName leads to stack-based buffer overflow. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-45538 1 Opensips 1 Opensips 2026-08-05 9.8 Critical
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. In versions 4.0.0 and prior, processing a SIP message with a header name longer than 255 bytes causes a stack buffer overflow when sip_to_json() is called in the routing script. Function sip_to_json() (modules/sipmsgops/sipmsgops.c) copies SIP header names into a fixed 255-byte stack buffer without bounds checking, performing a memcpy of the full header-name length even though the SIP parser imposes no such limit (a header name can be roughly 65000 bytes). As a result, when a routing script calls sip_to_json(), a SIP message with a header name longer than 255 bytes triggers a stack buffer overflow in which both the length and content of the overwrite are attacker-controlled, corrupting the saved frame pointer and return address. A single unauthenticated UDP packet to the SIP port (5060) can crash the process or, on builds without stack protections, hijack the return address to achieve remote code execution. This affects deployments whose routing script invokes sip_to_json(). This issue was not fixed at the time of publication.
CVE-2026-18895 1 Utt 1 Hiper 1250gw 2026-08-05 8.8 High
A vulnerability was found in UTT HiPER 1250GW up to 3.2.7-210907-180535. Impacted is the function strcpy of the file /goform/APSecurity_5g. Performing a manipulation of the argument cipher results in stack-based buffer overflow. It is possible to initiate the attack remotely. The exploit has been made public and could be used. The vendor was contacted early about this disclosure but did not respond in any way.
CVE-2026-61486 1 Apache 1 Lucy 2026-08-05 9.8 Critical
** UNSUPPORTED WHEN ASSIGNED ** Stack-based Buffer Overflow vulnerability in Apache Lucy. This issue affects Apache Lucy: all versions. As this project is retired, we do not plan to release a version that fixes this issue. Users are recommended to find an alternative or restrict access to the instance to trusted users. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
CVE-2026-45809 1 Opensips 1 Opensips 2026-08-05 N/A
OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions prior to 3.6.6 and 4.0.0-rc1 contain a denial of service vulnerability in the watcherinfo generation functionality. An attacker can create an oversized watcher entry by sending a SUBSCRIBE Event: presence request with a long From URI, and then trigger presence.winfo watcherinfo XML generation for the same presentity. OpenSIPS copies the stored watcher URI into a fixed-size stack buffer, overflowing it and crashing the process. A remote attacker can crash an OpenSIPS worker in deployments that expose handle_subscribe() and allow watcherinfo (presence.winfo) generation. The issue is configuration-dependent because the presence and presence_xml modules must be loaded and SUBSCRIBE routing must be reachable. This issue has been fixed in versions 3.6.6 and 4.0.0-rc1.
