SB2024021912 - Multiple vulnerabilities in Google ChromeOS TLS

Description

This security bulletin contains information about 8 secuirty vulnerabilities.

1) Integer overflow (CVE-ID: CVE-2023-6345)

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

The vulnerability exists due to integer overflow in Skia component in Google Chrome. A remote attacker can trick the victim to open a specially crafted web page, trigger an integer overflow and execute arbitrary code on the target system.

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

Note, the vulnerability is being actively exploited in the wild.

2) Use-after-free (CVE-ID: CVE-2024-0807)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error within the WebAudio component in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger use-after-free error and execute arbitrary code on the target system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

3) Integer underflow (CVE-ID: CVE-2024-0808)

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

The vulnerability exists due to integer underflow in WebUI. A remote attacker can trick the victim to open a specially crafted web page, trigger integer underflow and execute arbitrary code on the target system.

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

4) Use-after-free (CVE-ID: CVE-2023-51042)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the amdgpu_cs_wait_all_fences() function in drivers/gpu/drm/amd/amdgpu/amdgpu_cs.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.

5) Out-of-bounds write (CVE-ID: CVE-2023-6931)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a boundary error in the Linux kernel's Performance Events system component. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.

6) Use-after-free (CVE-ID: CVE-2023-6817)

The vulnerability allows a local authenticated user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the netfilter nf_tables component in Linux kernel. A local authenticated user can trigger a use-after-free error and escalate privileges on the system.

7) Improper access control (CVE-ID: CVE-2023-46813)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to improper access checking in the #VC handler and instruction emulation of the SEV-ES emulation of MMIO accesses. A local user can gain arbitrary write access to kernel memory and execute arbitrary code with elevated privileges.

8) Use-after-free (CVE-ID: CVE-2023-6932)

The vulnerability allows a local authenticated user to execute arbitrary code.

The vulnerability exists due to a use-after-free error within the ipv4 igmp component in Linux kernel. A local authenticated user can trigger a use-after-free error and execute arbitrary code.
