3) Out-of-bounds write

EUVDB-ID: #VU10968

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-5129

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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.

Mitigation

Install update from vendor's website.

5) Information disclosure

EUVDB-ID: #VU10970

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-5131

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The weakness exists due to the fetch() API can return transient local copies of resources that were sent with a no-store or no-cache cache header instead of downloading a copy from the network as it should. A remote attacker can share a common profile while browsing and access previously stored, locally cached data of a website.

Mitigation

Install update from vendor's website.
