Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2023-7024)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in WebRTC. 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.
Note, the vulnerability is being actively exploited in the wild.
2) Use-after-free (CVE-ID: CVE-2023-6508)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Media Stream 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) Use-after-free (CVE-ID: CVE-2023-6509)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Side Panel Search 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) Improperly implemented security check for standard (CVE-ID: CVE-2023-6511)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to incorrect implementation in Autofill in Google Chrome. A remote attacker can create a specially crafted web page, trick the victim into visiting it and gain access to sensitive information.
5) Input validation error (CVE-ID: CVE-2023-39191)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to insufficient validation of user-supplied input in the eBPF subsystem in the Linux kernel. A local user with CAP_BPF capability can execute arbitrary code with elevated privileges.
6) Out-of-bounds write (CVE-ID: N/A)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in PowerVR GPU Driver. A local application can trigger an out-of-bounds write and execute arbitrary code on the target system.
7) Out-of-bounds write (CVE-ID: N/A)
The vulnerability allows a local application to escalate privileges on the system.
The vulnerability exists due to a boundary error in PowerVR GPU Driver. A local application can trigger an out-of-bounds write and execute arbitrary code on the target system.
