Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2702-2 advisory.

 USN-2702-1 fixed vulnerabilities in Firefox. This update provides the corresponding updates for Ubufox.

 Original advisory details:

 Gary Kwong, Christian Holler, Byron Campen, Tyson Smith, Bobby Holley,

 Chris Coulson, and Eric Rahm discovered multiple memory safety issues in

 Firefox. 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 application crash, or execute arbitrary code with the privileges of

 the user invoking Firefox. (CVE-2015-4473, CVE-2015-4474)

 Aki Helin discovered an out-of-bounds read when playing malformed MP3

 content in some circumstances. If a user were tricked in to opening a

 specially crafted website, an attacker could potentially exploit this to

 obtain sensitive information, cause a denial of service via application

 crash, or execute arbitrary code with the privileges of the user invoking

 Firefox. (CVE-2015-4475)

 A use-after-free was discovered during MediaStream playback 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

 priviliges of the user invoking Firefox. (CVE-2015-4477)

 Andr Bargull discovered that non-configurable properties on javascript

 objects could be redefined when parsing JSON. If a user were tricked in to

 opening a specially crafted website, an attacker could potentially exploit

 this to bypass same-origin restrictions. (CVE-2015-4478)

 Multiple integer overflows were discovered in libstagefright. 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 application

 crash, or execute arbitrary code with the privileges of the user invoking

 Firefox. (CVE-2015-4479, CVE-2015-4480, CVE-2015-4493)

 Jukka Jylnki discovered a crash that occurs because javascript does not

 properly gate access to Atomics or SharedArrayBuffers 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-2015-4484)

 Abhishek Arya discovered 2 buffer overflows in libvpx when decoding

 malformed WebM content in some circumstances. 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 application crash, or

 execute arbitrary code with the privileges of the user invoking Firefox.

 (CVE-2015-4485, CVE-2015-4486)

 Ronald Crane reported 3 security issues. If a user were tricked in to

 opening a specially crafted website, an attacker could potentially

 exploit these, in combination with another security vulnerability, to

 cause a denial of service via application crash, or execute arbitrary

 code with the privileges of the user invoking Firefox. (CVE-2015-4487,

 CVE-2015-4488, CVE-2015-4489)

 Christoph Kerschbaumer discovered an issue with Mozilla's implementation

 of Content Security Policy (CSP), which could allow for a more permissive

 usage in some cirucumstances. An attacker could potentially exploit this

 to conduct cross-site scripting (XSS) attacks. (CVE-2015-4490)

 Gustavo Grieco discovered a heap overflow in gdk-pixbuf. 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 priviliges of the user invoking

 Firefox. (CVE-2015-4491)

 Looben Yang discovered a use-after-free when using XMLHttpRequest with

 shared workers 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 priviliges of the user invoking Firefox. (CVE-2015-4492)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
