Details

Several out-of-bounds write bugs were discovered in Skia. 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 application
crash or execute arbitrary code with the privileges of the user invoking
the program. (CVE-2015-1213, CVE-2015-1214, CVE-2015-1215)

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 with the privileges of the sandboxed render
process. (CVE-2015-1216)

Multiple type confusion bugs were discovered in the V8 bindings in Blink.
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-2015-1217, CVE-2015-1230)

Multiple use-after-free bugs were discovered in the DOM implementation in
Blink. 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-2015-1218, CVE-2015-1223)

An integer overflow was discovered in Skia. 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 with the privileges of the user invoking the program.
(CVE-2015-1219)

A use-after-free was discovered in the GIF image decoder 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 with the privileges of the sandboxed
render process. (CVE-2015-1220)

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 renderer crash, or execute
arbitrary code with the privileges of the sandboxed render process.
(CVE-2015-1221)

Multiple use-after-free bugs were discovered in the service worker
implementation in Chromium. 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 application crash or execute arbitrary
code with the privileges of the user invoking the program. (CVE-2015-1222)

An out-of-bounds read was discovered in the VPX decoder implementation in
Chromium. 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. (CVE-2015-1224)

It was discovered that Blink did not initialize memory for image drawing
in some circumstances. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to read
uninitialized memory. (CVE-2015-1227)

It was discovered that Blink did not initialize memory for a data
structure in some circumstances. 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-2015-1228)

It was discovered that a web proxy returning a 407 response could inject
cookies in to the originally requested domain. If a user connected to a
malicious web proxy, an attacker could potentially exploit this to conduct
session-fixation attacks. (CVE-2015-1229)

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-2015-1231)

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-2015-2238)
