9.3 - USN-2960-1

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 16.04 LTS - Ubuntu 15.10 - Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Oxide.

Software Description: - oxide-qt: Web browser engine for Qt (QML plugin)

Details:

An out of bounds write was discovered in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code. (CVE-2016-1660)

It was discovered that Blink assumes that a frame which passes same-origin checks is local in some cases. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code. (CVE-2016-1661)

A use-after-free was discovered in the V8 bindings in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code. (CVE-2016-1663)

It was discovered that the JSGenericLowering class in V8 mishandles comparison operators. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to obtain sensitive information. (CVE-2016-1665)

Multiple security issues were discovered in Chromium. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, cause a denial of service via application crash or execute arbitrary code. (CVE-2016-1666)

It was discovered that the TreeScope::adoptIfNeeded function in Blink does not prevent script execution during node-adoption operations. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2016-1667)

It was discovered that the forEachForBinding in the V8 bindings in Blink uses an improper creation context. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2016-1668)

A buffer overflow was discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code. (CVE-2016-1669)

A race condition was discovered in ResourceDispatcherHostImpl in Chromium. An attacker could potentially exploit this to make arbitrary HTTP requests. (CVE-2016-1670)

Update instructions:

The problem can be corrected by updating your system to the following package versions:

Ubuntu 16.04 LTS:
liboxideqtcore0 1.14.9-0ubuntu0.16.04.1

Ubuntu 15.10:
liboxideqtcore0 1.14.9-0ubuntu0.15.10.1

Ubuntu 14.04 LTS:
liboxideqtcore0 1.14.9-0ubuntu0.14.04.1

In general, a standard system update will make all the necessary changes.
