oxide-qt vulnerabilities
=========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10
- Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Oxide.
Software Description:
- oxide-qt: Web browser engine library for Qt (QML plugin)
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
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 application crash or execute arbitrary code with the
privileges of the user invoking the program. (CVE-2015-1317)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.10:
liboxideqtcore0 1.5.6-0ubuntu0.14.10.1
Ubuntu 14.04 LTS:
