Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2024-1283)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in Skia. A remote attacker can create a specially crafted web page, trick the victim into opening it, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
2) 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.
3) Use-after-free (CVE-ID: CVE-2024-1284)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Mojo 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.
4) Out-of-bounds write (CVE-ID: CVE-2024-0646)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error when processing untrusted input in the Linux kernel’s Transport Layer Security functionality in the way a user calls a function splice with a ktls socket as the destination. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
5) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-0611)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an unspecified error in the Linux kernel. A local user can execute arbitrary code with elevated privileges.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-6817)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an unspecified error in the Linux kernel. A local user can execute arbitrary code with elevated privileges.Remediation
