Details
A bad cast 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
with the privileges of the sandboxed render process. (CVE-2016-1612)
An issue was discovered when initializing the UnacceleratedImageBufferSurface
class in Blink. If a user were tricked in to opening a specially crafted
website, an attacker could potentially exploit this to obtain sensitive
information. (CVE-2016-1614)
An issue was discovered with the CSP implementation in Blink. If a user
were tricked in to opening a specially crafted website, an attacker could
potentially exploit this to determine whether specific HSTS sites had been
visited by reading a CSP report. (CVE-2016-1617)
An issue was discovered with random number generator in Blink. An attacker
could potentially exploit this to defeat cryptographic protection
mechanisms. (CVE-2016-1618)
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 with the
privileges of the user invoking the program. (CVE-2016-1620)
Multiple security issues were discovered in V8. 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
renderer crash or execute arbitrary code with the privileges of the
sandboxed render process. (CVE-2016-2051)
Multiple security issues were discovered in Harfbuzz. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service via renderer
crash or execute arbitrary code with the privileges of the sandboxed
render process. (CVE-2016-2052)
