CVE-2024-6918 2026-06-17 N/A 7.5 HIGH
CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability exists that could cause a crash of the Accutech Manager when receiving a specially crafted request over port 2536/TCP.
CVE-2024-6604 1 Mozilla 2 Firefox, Thunderbird 2026-06-17 N/A 7.5 HIGH
Memory safety bugs present in Firefox 127, Firefox ESR 115.12, and Thunderbird 115.12. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.
CVE-2024-6564 1 Renesas 1 Arm-trusted-firmware 2026-06-17 N/A 6.7 MEDIUM
Buffer overflow in "rcar_dev_init" due to using due to using untrusted data (rcar_image_number) as a loop counter before verifying it against RCAR_MAX_BL3X_IMAGE. This could lead to a full bypass of secure boot.
CVE-2024-6563 1 Renesas 1 Arm-trusted-firmware 2026-06-17 N/A 7.5 HIGH
Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Renesas arm-trusted-firmware allows Local Execution of Code. This vulnerability is associated with program files https://github.Com/renesas-rcar/arm-trusted-firmware/blob/rcar_gen3_v2.5/drivers/renesas/common/io/i... https://github.Com/renesas-rcar/arm-trusted-firmware/blob/rcar_gen3_v2.5/drivers/renesas/common/io/io_rcar.C . In line 313 "addr_loaded_cnt" is checked not to be "CHECK_IMAGE_AREA_CNT" (5) or larger, this check does not halt the function. Immediately after (line 317) there will be an overflow in the buffer and the value of "dst" will be written to the area immediately after the buffer, which is "addr_loaded_cnt". This will allow an attacker to freely control the value of "addr_loaded_cnt" and thus control the destination of the write immediately after (line 318). The write in line 318 will then be fully controlled by said attacker, with whichever address and whichever value ("len") they desire.
CVE-2024-6352 2026-06-17 N/A 4.3 MEDIUM
A malformed packet can cause a buffer overflow in the APS layer of the Ember ZNet stack and lead to an assert
CVE-2024-6351 2026-06-17 N/A 4.3 MEDIUM
A malformed packet can cause a buffer overflow in the NWK/APS layer of the Ember ZNet stack and lead to an assert
CVE-2024-6350 2026-06-17 N/A 6.5 MEDIUM
A malformed 802.15.4 packet causes a buffer overflow to occur leading to an assert and a denial of service. A watchdog reset clears the error condition automatically.
CVE-2024-6343 1 Zyxel 16 Atp100, Atp100w, Atp200 and 13 more 2026-06-17 N/A 4.9 MEDIUM
A buffer overflow vulnerability in the CGI program of Zyxel ATP series firmware versions from V4.32 through V5.38, USG FLEX series firmware versions from V4.50 through V5.38, USG FLEX 50(W) series firmware versions from V4.16 through V5.38, and USG20(W)-VPN series firmware versions from V4.16 through V5.38 could allow an authenticated attacker with administrator privileges to cause denial of service (DoS) conditions by sending a crafted HTTP request to a vulnerable device.
CVE-2024-6199 2026-06-17 N/A N/A
An unauthenticated attacker on the WAN interface, with the ability to intercept Dynamic DNS (DDNS) traffic between DDNS services and the modem, could manipulate specific responses to include code that forces a buffer overflow on the modem. Customers that have not enabled Dynamic DNS on their modem are not vulnerable.
CVE-2024-6198 2026-06-17 N/A N/A
The device exposes a web interface on ports TCP/3030 and TCP/9882. This web service runs lighttpd, which implements the “SNORE” interface. This interface is affected by a stack buffer overflow vulnerability due to insecure path parsing. An attacker with access to the LAN network interface could use a specially crafted HTTP request to exploit a buffer overflow on the modem.
CVE-2024-6143 1 Actiontec 2 Wcb6200q, Wcb6200q Firmware 2026-06-17 N/A 8.8 HIGH
Actiontec WCB6200Q uh_tcp_recv_header Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Actiontec WCB6200Q routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HTTP server. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to execute code in the context of the HTTP server. Was ZDI-CAN-21414.
CVE-2024-6142 1 Actiontec 2 Wcb6200q, Wcb6200q Firmware 2026-06-17 N/A 8.8 HIGH
Actiontec WCB6200Q uh_tcp_recv_content Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of Actiontec WCB6200Q routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the HTTP server. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length buffer. An attacker can leverage this vulnerability to execute code in the context of the HTTP server. Was ZDI-CAN-21410.
CVE-2024-5974 1 Watchguard 51 Firebox M200, Firebox M270, Firebox M290 and 48 more 2026-06-17 N/A 7.2 HIGH
A buffer overflow in WatchGuard Fireware OS could may allow an authenticated remote attacker with privileged management access to execute arbitrary code with system privileges on the firewall. This issue affects Fireware OS: from 11.9.6 through 12.10.3.
CVE-2024-5564 2026-06-17 N/A 8.1 HIGH
A vulnerability was found in libndp. This flaw allows a local malicious user to cause a buffer overflow in NetworkManager, triggered by sending a malformed IPv6 router advertisement packet. This issue occurred as libndp was not correctly validating the route length information.
CVE-2024-5463 1 Synology 4 Bc500, Bc500 Firmware, Tc500 and 1 more 2026-06-17 N/A 6.5 MEDIUM
A vulnerability regarding buffer copy without checking the size of input ('Classic Buffer Overflow') has been found in the login component. This allows remote attackers to write specific files containing non-sensitive information and conduct limited denial-of-service attacks via unspecified vectors. This attack only affects the login service which will automatically restart. The following models with Synology Camera Firmware versions before 1.1.1-0383 may be affected: BC500 and TC500.
CVE-2024-5412 1 Zyxel 100 Ax7501-b0, Ax7501-b0 Firmware, Ax7501-b1 and 97 more 2026-06-17 N/A 7.5 HIGH
A buffer overflow vulnerability in the library "libclinkc" of the Zyxel VMG8825-T50K firmware version 5.50(ABOM.8)C0 could allow an unauthenticated attacker to cause denial of service (DoS) conditions by sending a crafted HTTP request to a vulnerable device.
CVE-2024-5305 1 Tungstenautomation 1 Power Pdf 2026-06-17 N/A 7.8 HIGH
Kofax Power PDF PDF File Parsing Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Kofax Power PDF. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PDF files. 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-22921.
CVE-2024-5243 1 Tp-link 2 Omada Er605, Omada Er605 Firmware 2026-06-17 N/A 7.5 HIGH
TP-Link Omada ER605 Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. Authentication is not required to exploit this vulnerability. However, devices are vulnerable only if configured to use the Comexe DDNS service. The specific flaw exists within the handling of DNS names. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-22523.
