Description
This security bulletin contains information about 4 vulnerabilities.
1) Stack-based buffer overflow (CVE-ID: CVE-2026-7372)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within unconstrained sscanf in the WebCam Server functionality. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Stack-based buffer overflow (CVE-ID: CVE-2026-42369)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within unbound copy of base64 decoded string in the WebCam Server functionality. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
3) Stack-based buffer overflow (CVE-ID: CVE-2026-42370)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: 9.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the WebCam Server Login functionality. A remote unauthenticated attacker can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Stack-based buffer overflow (CVE-ID: CVE-2026-12488)
CWE-ID: CWE-121 - Stack-based buffer overflow
CVSSv4: 5.6 [CVSS:4.0/AV:N/AC:L/AT:P/PR:H/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the GV-Cloud functionality. A remote administrator can send a specially crafted network request, trigger stack-based buffer overflow and cause a denial of service on the target system.
