Description

This security bulletin contains information about 12 secuirty vulnerabilities.

1) Stack-based buffer overflow (CVE-ID: CVE-2025-7794)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the "fromNatStaticSetting" function in the /goform/NatStaticSetting file. A remote user 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-2025-7805)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the delno parameter in the fromPptpUserSetting function. A remote user 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-2025-7807)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the Go parameter in the fromSafeUrlFilter function. A remote user 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-2025-7806)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the Go parameter in the fromSafeClientFilter function. A remote user 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.

5) Stack-based buffer overflow (CVE-ID: CVE-2025-7796)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in the username parameter in the fromPptpUserAdd function. A remote user 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.

6) Stack-based buffer overflow (CVE-ID: CVE-2025-7434)
