Details
It was discovered that Chromium did not properly handle the interaction
of IPC, the gamepad API and V8. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit this to
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2015-1233)
A buffer overflow was discovered in the GPU service. 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. (CVE-2015-1234)
It was discovered that Oxide did not correctly manage the lifetime of
BrowserContext, resulting in a potential use-after-free in some

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-2015-1317)
