Multiple vulnerabilities have been disclosed in Mozilla’s Firefox browser and Thunderbird email client which could allow an attacker to conduct remote code execution, crash applications, leak sensitive information, or bypass the same-origin policy and other security restrictions.
Successful exploitation of these vulnerabilities could result in an attacker gaining the same privileges as the targeted user, and an attacker could install programs, tamper with data, or create new accounts.
Affected products include Mozilla Firefox versions prior to 39, Firefox ESR versions prior to 31.8, and Thunderbird versions prior to 38.1.
The risk to users of these products has been designated as “high” if they are redirected to a specially crafted webpage or open a specially crafted file, but no known exploits for the vulnerabilities have been detected in the wild yet.
A summary of the vulnerabilities include:
Multiple unspecified memory-corruption vulnerabilities that exist in the browser engine. [CVE-2015-2724, CVE-2015-2725, CVE-2015-2726]
A local security-bypass vulnerability because opening hyperlinks on a page with the mouse and specific keyboard key combinations could allow a Chrome privileged URL to be opened without context restrictions being preserved. [CVE 2015-2727]
A security-bypass vulnerability occurs due to an error in Network Security Services (NSS) where the client allows for a ECDHE_ECDSA exchange where the server does not send its ServerKeyExchange message instead of aborting the handshake. [CVE-2015-2721]
A privilege escalation vulnerability occurs due to broken behavior in Mozilla’s PDF file viewer. [CVE-2015-2743]
An information-disclosure vulnerability occurs while reviewing Firefox crash reports. This issue exists because the OS X crash reports contain the native key and key press information that was being entered when the crash occurred. [CVE-2015-2742]
A security-bypass vulnerability occurs when an overridable error is encountered. An attacker can exploit this issue to override a pinned certificate. [CVE-2015 2741]
Multiple unspecified memory-corruption vulnerabilities affect the applications. Specifically, these issues affect the ‘CairoTextureClientD3D9::BorrowDrawTarget’, ‘nsZipArchive::BuildFileList’, ‘rx::d3d11::SetBufferData’,’YCbCrImageDataDeserializer::ToDataSourceSurface’, ‘ArrayBufferBuilder::append’, ‘nsXMLHttpRequest::AppendToResponseText’ functions and ‘nsZipArchive.cpp’ source file. [CVE-2015-2734, CVE-2015-2735, CVE-2015-2736, CVE-2015-2737, CVE-2015-2738, CVE-2015-2739, CVE-2015-2740]
Multiple use-after-free vulnerabilities occur when using XMLHttpRequest in concert with either shared or dedicated workers. [CVE-2015-2722, CVE-2015-2723]
A security-bypass vulnerability occurs because Elliptical Curve Cryptography (ECC) multiplication for Elliptic Curve Digital Signature Algorithm (ECDSA) signature in Network Security Services (NSS) fails to handle certain signatures correctly. [CVE-2015-2730]
A use-after-free vulnerability occurs in Content Policy due to microtask execution error. [CVE-2015-2731]
An out-of-bound read vulnerability occurs while computing an oscillator rendering range in Web Audio. [CVE-2015-2729]
A memory corruption vulnerability occurs due to a type confusion in Indexed Database Manager. Specifically, this issue affects the ‘mozilla::dom::indexedDB::IndexedDatabaseManager()’ function. [CVE-2015-2728]
Users of these products are advised to apply appropriate updates provided by Mozilla Firefox and Thunderbird to vulnerable systems immediately, to run software without administrative privileges, and be wary of potentially malicious links and attachments in emails.
