Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Buffer overflow (CVE-ID: CVE-2018-5127)

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

The weakness exists due to buffer overflow when manipulating the SVg animatedPathSegList through script. A remote attacker can trick the victim into visiting a specially crafted website, trigger memory corruption and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

2) Out-of-bounds write (CVE-ID: CVE-2018-5129)

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

The weakness exists due to a lack of parameter validation on IPC messages. A remote attacker can supply specially crafted malformed IPC messages, trigger out-of-bounds write, escape sandbox and execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

3) Integer overflow (CVE-ID: CVE-2018-5144)

The vulnerability allows a remote attacker to cause DoS condition on the target system.

The weakness exists due to integer overflow during conversion of text to some Unicode character sets. A remote attacker can supply unchecked length parameter, trigger overflow and cause the service to crash.

4) Buffer overflow (CVE-ID: CVE-2018-5146)

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

The vulnerability exists due to boundary error when processing Vorbis audio within libvorbis library. A remote unauthenticated attacker can create a specially crafted HTML page, trick the victim into opening it, trigger out-of-bounds write and execute arbitrary code on the target system.

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

5) Memory corruption (CVE-ID: CVE-2018-5125)

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.

Successful exploitation of the vulnerability may result in system compromise.

6) Memory corruption (CVE-ID: CVE-2018-5145)

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.

Successful exploitation of the vulnerability may result in system compromise.
