Mozilla Firefox < 49.0 Multiple Vulnerabilities

High Nessus Network Monitor Plugin ID 9624

Synopsis

The remote host has a web browser installed that is vulnerable to multiple attack vectors.

Description

Versions of Mozilla Firefox prior to 49.0 are unpatched for the following vulnerabilities :

- A flaw exists as the certificate pinning policy for built-in sites like 'addons.mozilla.org' is not honored due to the pins having expired. This may allow a Man-in-the-Middle (MitM) attacker able to generate a trusted certificate to conduct spoofing attacks.
- A flaw exists in the 'CrossCompartmentWrapper::getPrototypeIfOrdinary()' function in 'js/src/proxy/CrossCompartmentWrapper.cpp' that is triggered as certain input is not properly validated. With a specially crafted web page, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.
- A use-after-free error exists in 'dom/media/systemservices/LoadManager.h' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A flaw exists in the 'imgFrame::InitForDecoder()' function in 'image/imgFrame.cpp' that is triggered when handling paletted images. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in the 'GenerateCallGetter()' function in 'jit/IonCaches.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- An unspecified flaw exists in 'dom/media/platforms/wmf/WMFVideoMFTManager.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in 'netwerk/sctp/src/netinet/sctputil.c' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in the WebRTC component that is triggered as certain input is not properly validated when handling H.264 STAP-A content. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in the 'nsNodeUtils::CloneAndAdopt()' function in 'dom/base/nsNodeUtils.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in the 'parse()' function in 'libavcodec/vp9_parser.c' that is triggered when handling input frame sizes. This may allow a context-dependent attacker to corrupt memory, crashing a process linked against the library and potentially allowing the execution of arbitrary code.
- An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in 'netwerk/sctp/src/netinet/sctputil.c' that is triggered when handling association failures. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A flaw exists in the 'nsHttpChannelAuthProvider::OnAuthCancelled()' function in 'netwerk/protocol/http/nsHttpChannelAuthProvider.cpp' that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- An unspecified flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- An unspecified flaw exists that may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. No further details have been provided by the vendor.
- A flaw exists that is triggered as certain input is not properly validated when handling APNG images. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
- A use-after-free error exists that is triggered when handling SVG format content being manipulated through script code. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A use-after-free error exists in the 'nsTextNodeDirectionalityMap::RemoveElementFromMap()' function in 'dom/base/DirectionalityUtils.cpp' that is triggered when handling changing of text direction. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A flaw exists when handling content that requests favicons from non-whitelisted schemes using certain URI handlers e.g. jar:. This may allow a context-dependent attacker to bypass intended restrictions.
- A use-after-free error exists in the 'nsRefreshDriver::Tick()' function that is triggered when handling web animations destroying a timeline. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A type confusion flaw exists in 'layout/forms/nsRangeFrame.cpp' that triggered when handling layout with input elements. This may allow a context-dependent attacker to potentially execute arbitrary code.
- An overflow condition exists in the 'FilterSupport::ComputeSourceNeededRegions()' function that is triggered when handling empty filters during canvas rendering. This may allow a context-dependent attacker to cause a global-based buffer overflow and potentially execute arbitrary code.
- An overflow condition exists in the 'nsCaseTransformTextRunFactory::TransformString()' function in 'layout/generic/nsTextRunTransformations.cpp' that is triggered when converting text containing certain unicode characters. This may allow a context-dependent attacker to cause a heap-based buffer overflow, potentially allowing the execution of arbitrary code.
- A flaw exists that is triggered when handling drag-and-drop events for files. This may allow a context-dependent attacker to gain knowledge of the full local file path.
- An out-of-bounds read flaw exists in 'dom/security/nsCSPParser.cpp' that is triggered when handling content security policies (CSP) containing empty referrer directives. This may allow a context-dependent attacker to cause a crash.
- A flaw exists related to the handling of iframes. This may allow a context-dependent attacker to conduct an 'iframe src' fragment timing attack that discloses cross-origin data.
- An overflow condition exists in the 'nsBMPEncoder::AddImageFrame()' function in 'dom/base/ImageEncoder.cpp' that is triggered when encoding image frames to images. This may allow a context-dependent attacker to cause a heap-based buffer overflow and potentially execute arbitrary code.
- A use-after-free error exists in the 'DocAccessible::ProcessInvalidationList()' function in 'accessible/generic/DocAccessible.cpp' that is triggered when setting an aria-owns attribute. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- A use-after-free error exists in 'layout/style/nsRuleNode.cpp' that is triggered when handling web animations during restyling. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code.
- An unspecified flaw exists in the 'HyperTextAccessible::GetChildOffset()' function. This may allow a context-dependent attacker to potentially execute arbitrary code.
- An out-of-bounds read flaw exists in the 'nsCSSFrameConstructor::GetInsertionPrevSibling()' function in 'layout/base/nsCSSFrameConstructor.cpp' that is triggered when handling text runs. This may allow a context-dependent attacker to potentially disclose memory contents.

Solution

Upgrade to Firefox version 49.0 or later.
