or possibly execute arbitrary code with user privileges. (CVE-2014-8138)

It was discovered that JasPer incorrectly handled certain malformed
JPEG-2000 image files. If a user were tricked into opening a specially
crafted JPEG-2000 image file, a remote attacker could cause JasPer to crash
or possibly execute arbitrary code with user privileges. (CVE-2014-8157)

It was discovered that JasPer incorrectly handled memory when processing
JPEG-2000 image files. If a user were tricked into opening a specially

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.
