CVE-2024-48406	Cri	0.64	9.8	0.00	Nov 29, 2024	Buffer Overflow vulnerability in SunBK201 umicat through v.0.3.2 and fixed in v.0.3.3 allows an attacker to execute arbitrary code via the power(uct_int_t x, uct_int_t n) in src/uct_upstream.c.
CVE-2015-20111	Cri	0.64	9.8	0.04	Nov 18, 2024	miniupnp before 4c90b87, as used in Bitcoin Core before 0.12 and other products, lacks checks for snprintf return values, leading to a buffer overflow and significant data leak, a different vulnerability than CVE-2019-12107. In Bitcoin Core before 0.12, remote code execution was possible in conjunction with CVE-2015-6031 exploitation.
CVE-2024-45746	Cri	0.64	9.8	0.09	Oct 9, 2024	An issue was discovered in Trusted Firmware-M through 2.1.0. User provided (and controlled) mailbox messages contain a pointer to a list of input arguments (in_vec) and output arguments (out_vec). These list pointers are never validated. Each argument list contains a buffer pointer and a buffer length field. After a PSA call, the length of the output arguments behind the unchecked pointer is updated in mailbox_direct_reply, regardless of the call result. This allows an attacker to write anywhere in the secure firmware, which can be used to take over the control flow, leading to remote code execution (RCE).
CVE-2024-40568	Cri	0.64	9.8	0.02	Sep 18, 2024	Buffer Overflow vulnerability in btstack mesh commit before v.864e2f2b6b7878c8fab3cf5ee84ae566e3380c58 allows a remote attacker to execute arbitrary code via the pb_adv_handle_tranaction_cont function in the src/mesh/pb_adv.c component
CVE-2024-41660	Cri	0.64	9.8	0.00	Jul 31, 2024	slpd-lite is a unicast SLP UDP server. Any OpenBMC system that includes the slpd-lite package is impacted. Installing this package is the default when building OpenBMC. Nefarious users can send slp packets to the BMC using UDP port 427 to cause memory overflow issues within the slpd-lite daemon on the BMC. Patches will be available in the latest openbmc/slpd-lite repository.
CVE-2024-4143	Cri	0.64	9.8	0.00	Jul 15, 2024	A potential security vulnerability has been identified in certain HP PC products using AMI BIOS, which might allow arbitrary code execution. AMI has released firmware updates to mitigate this vulnerability.
CVE-2024-33278	Cri	0.64	9.8	0.04	Jun 24, 2024	Buffer Overflow vulnerability in ASUS router RT-AX88U with firmware versions v3.0.0.4.388_24198 allows a remote attacker to execute arbitrary code via the connection_state_machine due to improper length validation for the cookie field.
CVE-2022-32504	Cri	0.64	9.8	0.00	May 14, 2024	An issue was discovered on certain Nuki Home Solutions devices. The code used to parse the JSON objects received from the WebSocket service provided by the device leads to a stack buffer overflow. An attacker would be able to exploit this to gain arbitrary code execution on a KeyTurner device. This affects Nuki Smart Lock 3.0 before 3.3.5 and 2.0 before 2.12.4, as well as Nuki Bridge v1 before 1.22.0 and v2 before 2.13.2.
CVE-2024-3871	Cri	0.64	9.8	0.03	Apr 16, 2024	The Delta Electronics DVW-W02W2-E2 devices expose a web administration interface to users. This interface implements multiple features that are affected by command injections and stack overflows vulnerabilities. Successful exploitation of these flaws would allow remote unauthenticated attackers to gain remote code execution with elevated privileges on the affected devices. This issue affects DVW-W02W2-E2 through version 2.5.2.
CVE-2016-5343	Cri	0.64	9.8	0.01	Oct 10, 2016	drivers/soc/qcom/qdsp6v2/voice_svc.c in the QDSP6v2 Voice Service driver for the Linux kernel 3.x, as used in Qualcomm Innovation Center (QuIC) Android contributions for MSM devices and other products, allows attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a write request, as demonstrated by a voice_svc_send_req buffer overflow.
CVE-2016-4303	Cri	0.64	9.8	0.06	Sep 26, 2016	The parse_string function in cjson.c in the cJSON library mishandles UTF8/16 strings, which allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a non-hex character in a JSON string, which triggers a heap-based buffer overflow.
CVE-2016-4002	Cri	0.64	9.8	0.08	Apr 26, 2016	Buffer overflow in the mipsnet_receive function in hw/net/mipsnet.c in QEMU, when the guest NIC is configured to accept large packets, allows remote attackers to cause a denial of service (memory corruption and QEMU crash) or possibly execute arbitrary code via a packet larger than 1514 bytes.
CVE-2014-1524	Cri	0.64	9.8	0.06	Apr 30, 2014	The nsXBLProtoImpl::InstallImplementation function in Mozilla Firefox before 29.0, Firefox ESR 24.x before 24.5, Thunderbird before 24.5, and SeaMonkey before 2.26 does not properly check whether objects are XBL objects, which allows remote attackers to execute arbitrary code or cause a denial of service (buffer overflow) via crafted JavaScript code that accesses a non-XBL object as if it were an XBL object.
CVE-2006-6024	Cri	0.64	9.8	0.00	Nov 21, 2006	Multiple buffer overflows in Eudora Worldmail, possibly Worldmail 3 version 6.1.22.0, have unknown impact and attack vectors, as demonstrated by the (1) "Eudora WorldMail stack overflow" and (2) "Eudora WorldMail heap overflow" modules in VulnDisco Pack. NOTE: Some of these details are obtained from third party information. As of 20061118, this disclosure has no actionable information. However, because the VulnDisco Pack author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes.
CVE-2011-10022	Hig	0.63	—	0.54	Aug 20, 2025	SPlayer version 3.7 and earlier is vulnerable to a stack-based buffer overflow when processing HTTP responses containing an overly long Content-Type header. The vulnerability occurs due to improper bounds checking on the header value, allowing an attacker to overwrite the Structured Exception Handler (SEH) and execute arbitrary code. Exploitation requires the victim to open a media file that triggers an HTTP request to a malicious server, which responds with a crafted Content-Type header.
