A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 15.04
- 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:
An uninitialized value issue was discovered in ICU. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to cause a denial of service. (CVE-2015-1270)
A use-after-free was discovered in the GPU process 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 application crash, or execute arbitrary code with the
privileges of the user invoking the program. (CVE-2015-1272)
A use-after-free was discovered in the IndexedDB 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 application crash, or execute arbitrary code with the
privileges of the user invoking the program. (CVE-2015-1276)
A use-after-free was discovered in the accessibility implemetation 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 application crash, or execute arbitrary code with the
privileges of the user invoking the program. (CVE-2015-1277)
A memory corruption issue 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, or execute
arbitrary code with the privileges of the sandboxed render process.
(CVE-2015-1280)
It was discovered that Blink did not properly determine the V8 context of=
a microtask in some circumstances. If a user were tricked in to opening a=
specially crafted website, an attacker could potentially exploit this to
bypass Content Security Policy (CSP) restrictions. (CVE-2015-1281)
Multiple integer overflows were discovered in Expat. 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-2015-1283)
It was discovered that Blink did not enforce a page's maximum number of=20
frames in some circumstances, resulting in a use-after-free. 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-2015-1284)
It was discovered that the XSS auditor in Blink did not properly choose a=
truncation point. If a user were tricked in to opening a specially crafte=
d
website, an attacker could potentially exploit this to obtain sensitive
information. (CVE-2015-1285)
An issue was discovered in the CSS implementation in Blink. If a user wer=
e
tricked in to opening a specially crafted website, an attacker could
potentially exploit this to bypass same-origin restrictions.
(CVE-2015-1287)
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-2015-1289)
A use-after-free was discovered in oxide::qt::URLRequestDelegatedJob 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-2015-1329)
A crash was discovered in the regular expression implementation in V8 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. (CVE-2015-5605)
Update instructions:
The problem can be corrected by updating your system to the following
