SB2024081377 - Multiple vulnerabilities in Microsoft Windows Routing and Remote Access Service (RRAS)

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Heap-based buffer overflow (CVE-ID: CVE-2024-38130)

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

The vulnerability exists due to a boundary error in Windows Routing and Remote Access Service (RRAS). A remote attacker can trick a victim to connect to a malicious server, trigger a heap-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) Heap-based buffer overflow (CVE-ID: CVE-2024-38120)

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

The vulnerability exists due to a boundary error in Windows Routing and Remote Access Service (RRAS). A remote attacker can trick a victim to connect to a malicious server, trigger a heap-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) Out-of-bounds read (CVE-ID: CVE-2024-38214)

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition in Windows Routing and Remote Access Service (RRAS). A remote attacker can trigger an out-of-bounds read error and read contents of memory on the system.

4) Integer overflow (CVE-ID: CVE-2024-38128)

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

The vulnerability exists due to integer overflow in Windows Routing and Remote Access Service (RRAS). A remote attacker can trick a victim to connect to a malicious server, trigger integer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

5) Heap-based buffer overflow (CVE-ID: CVE-2024-38121)

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

The vulnerability exists due to a boundary error in Windows Routing and Remote Access Service (RRAS). A remote attacker can trick a victim to connect to a malicious server, trigger a heap-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) Heap-based buffer overflow (CVE-ID: CVE-2024-38154)

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

The vulnerability exists due to a boundary error in Windows Routing and Remote Access Service (RRAS). A remote attacker can trick a victim to connect to a malicious server, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
