Description
This security bulletin contains information about 10 secuirty vulnerabilities.
1) Use-after-free (CVE-ID: CVE-2016-5824)
The vulnerability allows a remote attacker to perform denial of service attack.
The vulnerability exists due to a use-after-free error when processing ics Calendar files. A remote attackers can trick the victim to open a specially crafted calendar file, trigger user-after-free error and crash the affected application.
2) Memory corruption (CVE-ID: CVE-2018-12405)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to boundary error when handling malicious input. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
3) Memory corruption (CVE-ID: CVE-2018-17466)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to boundary error in Angle. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation on the vulnerability may result in system compromise.
4) Use-after-free error (CVE-ID: CVE-2018-18492)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to use-after-free error after deleting a selection element due to a weak reference to the
select element in the options collection.. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.Successful exploitation of the vulnerability may result in system compromise.
5) Buffer overflow (CVE-ID: CVE-2018-18493)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to boundary error in the Skia library during buffer offset calculations with hardware accelerated canvas 2D actions due to the use of 32-bit calculations instead of 64-bit. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
6) Same-origin policy bypass (CVE-ID: CVE-2018-18494)
The vulnerability allows a remote attacker to bypass same-origin policy on the target system.The weakness exists due to an error .when using the Javascript
location property. A remote attacker can trick the victim into visiting a specially crafted website and theft cross-origin URL entries to cause a redirection to another site using performance.getEntries(). 7) Integer overflow (CVE-ID: CVE-2018-18498)
The vulnerability allows a remote attacker to cause DoS condition on the target system.The weakness exists due to an integer overflow during buffer size calculations for images. A remote attacker can use a raw value instead of the checked value, trigger out-of-bounds read and cause the service to crash.
8) Use-after-free (CVE-ID: CVE-2018-18500)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error when HTML5 stream in concert with custom HTML elements. 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.
9) Buffer overflow (CVE-ID: CVE-2018-18501)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error when processing HTML content. A remote attacker can create a specially crafted web page, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2018-18505)
The vulnerability allows a remote attacker to bypass imposed sandbox restrictions.
The vulnerability exists within implementation of authentication process for Inter-process Communication (IPC). This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. A remote attacker can bypass sandbox restrictions through IPC channels due to lack of message validation in the listener process.
