========================================================================== Ubuntu Security Notice USN-2960-1 May 18, 2016
oxide-qt vulnerabilities ==========================================================================
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.
