Description
This security bulletin contains information about 7 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2023-5472)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error within the Profiles 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.
2) Improperly implemented security check for standard (CVE-ID: CVE-2023-5481)
The vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to incorrect implementation in Downloads 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.
3) Heap-based buffer overflow (CVE-ID: CVE-2023-5474)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a boundary error when processing untrusted HTML content in PDF. 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.
4) Input validation error (CVE-ID: CVE-2023-35688)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an unspecified vulnerability in Linux kernel. A local user can execute arbitrary code with elevated privileges.
5) Input validation error (CVE-ID: CVE-2023-21401)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an unspecified vulnerability in Linux kernel. A local user can execute arbitrary code with elevated privileges.
6) Input validation error (CVE-ID: CVE-2023-21263)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an unspecified vulnerability in Linux kernel. A local user can execute arbitrary code with elevated privileges.
7) Heap-based buffer overflow (CVE-ID: CVE-2023-38545)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the SOCKS5 proxy handshake. A remote attacker can trick the victim to visit a malicious website, 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 but requires that SOCKS5 proxy is used and that SOCKS5 handshake is slow (e.g. under heavy load or DoS attack).
