Firefox ESR < 31.8 Multiple Vulnerabilities (Mac OS X) (Logjam)

critical Nessus Plugin ID 84575

Language:

Synopsis

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

Description

The version of Firefox ESR installed on the remote Mac OS X host i 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.
