Details

Several memory corruption bugs were discovered in ICU. 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-2014-7923, CVE-2014-7926)

A use-after-free was discovered in the IndexedDB implementation. 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-2014-7924)

A use-after free was discovered in the WebAudio 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
renderer crash or execute arbitrary code with the privileges of the
sandboxed render process. (CVE-2014-7925)

Several memory corruption bugs were discovered in V8. 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-2014-7927, CVE-2014-7928, CVE-2014-7931)

Several 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-2014-7929, CVE-2014-7930, CVE-2014-7932,
CVE-2014-7934)

A use-after free was discovered in FFmpeg. 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-2014-7933)

Multiple off-by-one errors were discovered in FFmpeg. 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-2014-7937)

A memory corruption bug was discovered in the fonts implementation. 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-2014-7938)

It was discovered that ICU did not initialize memory for a data structure
correctly. 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-2014-7940)

It was discovered that the fonts implementation did not initialize memory
for a data structure correctly. 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-2014-7942)

An out-of-bounds read 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 renderer crash. (CVE-2014-7943)

An out-of-bounds read 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. (CVE-2014-7946)

It was discovered that the AppCache proceeded with caching for SSL
sessions even if there is a certificate error. A remote attacker could
potentially exploit this by conducting a MITM attack to modify HTML
application content. (CVE-2014-7948)

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-2015-1205)

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-2015-1346)
