Ubuntu Security Notice USN-2476-1
January 26, 2015
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:
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)
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 14.10:
liboxideqtcore0 1.4.2-0ubuntu0.14.10.1
oxideqt-codecs 1.4.2-0ubuntu0.14.10.1
oxideqt-codecs-extra 1.4.2-0ubuntu0.14.10.1
Ubuntu 14.04 LTS:
liboxideqtcore0 1.4.2-0ubuntu0.14.04.1
oxideqt-codecs 1.4.2-0ubuntu0.14.04.1
oxideqt-codecs-extra 1.4.2-0ubuntu0.14.04.1
In general, a standard system update will make all the necessary changes.
