A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in Oxide.
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)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
