A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in Oxide.
An issue was discovered in Blink involving the provisional URL for an initially empty document. An attacker could potentially exploit this to spoof the currently displayed URL. (CVE-2016-5141)
A use-after-free was discovered in the WebCrypto implementation 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 application crash, or execute arbitrary code. (CVE-2016-5142)
It was discovered that the devtools subsystem in Blink mishandles various parameters. An attacker could exploit this to bypass intended access restrictions. (CVE-2016-5143, CVE-2016-5144)
It was discovered that Blink does not ensure that a taint property is preserved after a structure-clone operation on an ImageBitmap object derived from a cross-origin image. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to bypass same origin restrictions. (CVE-2016-5145)
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-2016-5146, CVE-2016-5167)
It was discovered that Blink mishandles deferred page loads. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2016-5147)
An issue was discovered in Blink related to widget updates. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2016-5148)
A use-after-free 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 application crash, or execute arbitrary code. (CVE-2016-5150)
A use-after-free 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 application crash, or execute arbitrary code. (CVE-2016-5153)
It was discovered that Chromium does not correctly validate access to the initial document. An attacker could potentially exploit this to spoof the currently displayed URL. (CVE-2016-5155)
A use-after-free was discovered in the event 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 application crash, or execute arbitrary code. (CVE-2016-5156)
A type confusion bug 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 application crash, or execute arbitrary code. (CVE-2016-5161)
An issue was discovered with the devtools implementation. An attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2016-5164)
An issue was discovered with the devtools implementation. An attacker could potentially exploit this to conduct cross-site scripting (XSS) attacks. (CVE-2016-5165)
