Mozilla Firefox < 49.0 Multiple Vulnerabilities (Mac OS X)

High Nessus Plugin ID 93660

Synopsis

The remote Mac OS X host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Mozilla Firefox installed on the remote Mac OS X host is prior to 49.0. It is, therefore, affected by multiple vulnerabilities :

- An out-of-bounds read error exists within file dom/security/nsCSPParser.cpp when handling content security policies (CSP) containing empty referrer directives. An unauthenticated, remote attacker can exploit this to cause a denial of service condition.
(CVE-2016-2827)

- Multiple memory safety issues exist that allow an unauthenticated, remote attacker to potentially execute arbitrary code. (CVE-2016-5256, CVE-2016-5257)

- A heap buffer overflow condition exists in the nsCaseTransformTextRunFactory::TransformString() function in layout/generic/nsTextRunTransformations.cpp when converting text containing certain Unicode characters. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5270)

- An out-of-bounds read error exists in the nsCSSFrameConstructor::GetInsertionPrevSibling() function in file layout/base/nsCSSFrameConstructor.cpp when handling text runs. An unauthenticated, remote attacker can exploit this to disclose memory contents.
(CVE-2016-5271)

- A type confusion error exists within file layout/forms/nsRangeFrame.cpp when handling layout with input elements. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5272)

- An unspecified flaw exists in the HyperTextAccessible::GetChildOffset() function that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2016-5273)

- A use-after-free error exists within file layout/style/nsRuleNode.cpp when handling web animations during restyling. An unauthenticated, remote attacker can exploit this to execute arbitrary code.
(CVE-2016-5274)

- A buffer overflow condition exists in the FilterSupport::ComputeSourceNeededRegions() function when handling empty filters during canvas rendering. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5275)

- A use-after-free error exists in the DocAccessible::ProcessInvalidationList() function within file accessible/generic/DocAccessible.cpp when setting an aria-owns attribute. An unauthenticated, remote attacker can exploit this to execute arbitrary code.
(CVE-2016-5276)

- A use-after-free error exists in the nsRefreshDriver::Tick() function when handling web animations destroying a timeline. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5277)

- A buffer overflow condition exists in the nsBMPEncoder::AddImageFrame() function within file dom/base/ImageEncoder.cpp when encoding image frames to images. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5278)

- A flaw exists that is triggered when handling drag-and-drop events for files. An unauthenticated, remote attacker can exploit this disclose the full local file path. (CVE-2016-5279)

- A use-after-free error exists in the nsTextNodeDirectionalityMap::RemoveElementFromMap() function within file dom/base/DirectionalityUtils.cpp when handling changing of text direction. An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5280)

- A use-after-free error exists when handling SVG format content that is being manipulated through script code.
An unauthenticated, remote attacker can exploit this to execute arbitrary code. (CVE-2016-5281)

- A flaw exists when handling content that requests favicons from non-whitelisted schemes that are using certain URI handlers. An unauthenticated, remote attacker can exploit this to bypass intended restrictions. (CVE-2016-5282)

- A flaw exists that is related to the handling of iframes that allow an unauthenticated, remote attacker to conduct an 'iframe src' fragment timing attack, resulting in disclosure of cross-origin data.
(CVE-2016-5283)

- A flaw exists due to the certificate pinning policy for built-in sites (e.g., addons.mozilla.org) not being honored when pins have expired. A man-in-the-middle (MitM) attacker can exploit this to generate a trusted certificate, which could be used to conduct spoofing attacks. (CVE-2016-5284)

Solution

Upgrade to Mozilla Firefox version 49.0 or later.
