Firefox ESR < 38.5 Multiple Vulnerabilities (Mac OS X)

critical Nessus Plugin ID 87473

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 is prior to 38.5. It is, therefore, affected by the following vulnerabilities :

 - Multiple unspecified memory corruption issues exist due to improper validation of user-supplied input. A remote attacker can exploit these issues by convincing a user to visit a specially crafted web page, resulting in the execution of arbitrary code. (CVE-2015-7201)

 - A flaw exists in the RtpHeaderParser::Parse() function due to improper handling of RTP headers. An unauthenticated, remote attacker can exploit this, via specially crafted RTP headers, to execute arbitrary code. (CVE-2015-7205)

 - A use-after-free error exists due to improper prevention of datachannel operations on closed PeerConnections. An attacker can exploit this to dereference already freed memory, resulting in the execution of arbitrary code.
 (CVE-2015-7210)

 - An overflow condition exists in the AllocateForSurface() function due to improper validation of user-supplied input when handling texture allocation in graphics operations. An attacker can exploit this to execute arbitrary code. (CVE-2015-7212)

 - An integer overflow condition exists in the readMetaData() function due to improper validation of user-supplied input when handling a specially crafted MP4 file. An attacker can exploit this to execute arbitrary code. (CVE-2015-7213)

 - A same-origin bypass vulnerability exists due to improper handling of 'data:' and 'view-source:' URIs. An attacker can exploit this to read data from cross-site URLs and local files. (CVE-2015-7214)

 - An integer underflow condition exists in the bundled version of libstagefright in the parseChunk() function that is triggered when handling 'covr' chunks. An unauthenticated, remote attacker can exploit this, via specially crafted media content, to crash the application or execute arbitrary code. (CVE-2015-7222)

Solution

Upgrade to Firefox ESR 38.5 or later.
