Synopsis

The remote Ubuntu host is missing a security-related patch.

Description

A crash was discovered in TransportSecurityInfo used for SSL, which could be triggered by data stored in the local cache directory. An attacker could potentially exploit this in combination with another vulnerability that allowed them to write data to the cache, to execute arbitrary code. (CVE-2018-12385)

A type confusion bug was discovered in JavaScript. If a user were tricked in to opening a specially crafted website, an attacker could exploit this to cause a denial of service, or execute arbitrary code.
(CVE-2018-12386)

It was discovered that the Array.prototype.push could leak memory addresses to the calling function in some circumstances. An attacker could exploit this in combination with another vulnerability to help execute arbitrary code. (CVE-2018-12387).
