(CVE-2016-5257)

Atte Kettunen discovered a heap buffer overflow during text conversion with some unicode characters. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5270)

Abhishek Arya discovered a bad cast when processing layout with input elements in some circumstances. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5272)

A use-after-free was discovered in web animations during restyling. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5274)

A use-after-free was discovered in accessibility. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5276)

A use-after-free was discovered in web animations when destroying a timeline. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5277)

A buffer overflow was discovered when encoding image frames to images in some circumstances. If a user were tricked in to opening a specially crafted message, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5278)

Mei Wang discovered a use-after-free when changing text direction. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code. (CVE-2016-5280)

Brian Carpenter discovered a use-after-free when manipulating SVG content in some circumstances. If a user were tricked in to opening a specially crafted website in a browsing context, an attacker could potentially exploit this to cause a denial of service via application crash, or execute arbitrary code.
