to obtain sensitive information. (CVE-2016-5250)
Christoph Diehl, Andrew McCreight, Dan Minor, Byron Campen, Jon Coppeard,
Steve Fink, Tyson Smith, and Carsten Book discovered multiple memory
safety issues in Thunderbird. If a user were tricked in to opening a

cause a denial of service via application crash, or execute arbitrary
code. (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

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
