Firefox ESR < 31.8 Multiple Vulnerabilities (Logjam)

critical Nessus Plugin ID 84579

Language:

Synopsis

The remote Windows host contains a web browser that is affected by multiple vulnerabilities.

Description

The version of Firefox ESR installed on the remote Windows host is prior to 31.8. It is, therefore, affected by multiple vulnerabilities :

 - A security downgrade vulnerability exists due to a flaw in Network Security Services (NSS). When a client allows for a ECDHE_ECDSA exchange, but the server does not send a ServerKeyExchange message, the NSS client will take the EC key from the ECDSA certificate. A remote attacker can exploit this to silently downgrade the exchange to a non-forward secret mixed-ECDH exchange. (CVE-2015-2721)

 - Multiple user-after-free errors exist when using an XMLHttpRequest object in concert with either shared or dedicated workers. A remote attacker can exploit this to cause a denial of service condition. (CVE-2015-2722, CVE-2015-2733)

 - Multiple memory corruption issues exist that allow an attacker to cause a denial of service condition or potentially execute arbitrary code. (CVE-2015-2724)

 - A type confusion flaw exists in the Indexed Database Manager's handling of IDBDatabase. A remote attacker can exploit this to cause a denial of service condition or to execute arbitrary code. (CVE-2015-2728)

 - A signature spoofing vulnerability exists due to a flaw in Network Security Services (NSS) in its Elliptic Curve Digital Signature Algorithm (ECDSA) signature validation. A remote attacker can exploit this to forge signatures. (CVE-2015-2730)

 - An uninitialized memory use issue exists in the CairoTextureClientD3D9::BorrowDrawTarget() function, the ::d3d11::SetBufferData() function, and the YCbCrImageDataDeserializer::ToDataSourceSurface() function. The impact is unspecified. (CVE-2015-2734, CVE-2015-2737, CVE-2015-2738)

 - A memory corruption issue exists in the nsZipArchive::GetDataOffset() function due to improper string length checks. An attacker can exploit this, via a crafted ZIP archive, to potentially execute arbitrary code. (CVE-2015-2735)

 - A memory corruption issue exists in the nsZipArchive::BuildFileList() function due to improper validation of user-supplied input. An attacker can exploit this, via a crafted ZIP archive, to potentially execute arbitrary code. (CVE-2015-2736)

 - An unspecified memory corruption issue exists in the ArrayBufferBuilder::append() function due to improper validation of user-supplied input. An attacker can exploit this to potentially execute arbitrary code.
 (CVE-2015-2739)

 - A buffer overflow condition exists in the nsXMLHttpRequest::AppendToResponseText() function due to improper validation of user-supplied input. An attacker can exploit this to potentially execute arbitrary code.
 (CVE-2015-2740)

 - A privilege escalation vulnerability exists in the PDF viewer (PDF.js) due to internal workers being executed insecurely. An attacker can exploit this, by leveraging a Same Origin Policy bypass, to execute arbitrary code.
 (CVE-2015-2743)

 - A man-in-the-middle vulnerability, known as Logjam, exists due to a flaw in the SSL/TLS protocol. A remote attacker can exploit this flaw to downgrade connections using ephemeral Diffie-Hellman key exchange to 512-bit export-grade cryptography. (CVE-2015-4000)

Solution

Upgrade to Firefox ESR 31.8 or later.
