Mozilla Firefox ESR < 31.7 Multiple Vulnerabilities

Versions of Mozilla Firefox ESR prior to 31.7 are unpatched for the following vulnerabilities :

• A privilege escalation vulnerability exists in the Inter-process Communications (IPC) implementation due to a failure to validate the identity of a listener process. (MFSA2015-57)
• An issue exists in the Mozilla updater in which DLL files in the current working directory or Windows temporary directories will be loaded, allowing the execution of arbitrary code. (CVE-2015-0833, CVE-2015-2720)
• Multiple memory corruption issues exist within the browser engine. A remote attacker can exploit these to corrupt memory and execute arbitrary code. (CVE-2015-2708, CVE-2015-2709)
• A buffer overflow condition exists in ‘SVGTextFrame.cpp’ when rendering SVG graphics that are combined with certain CSS properties due to improper validation of user-supplied input. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-2710)
• A security bypass vulnerability exists due to the referrer policy not being enforced in certain situations when opening links (e.g. using the context menu or a middle-clicks by mouse). A remote attacker can exploit this to bypass intended policy settings. (CVE-2015-2711)
• An out-of-bounds read and write issue exists in the ‘CheckHeapLengthCondition()’ function due to improper JavaScript validation of heap lengths. A remote attacker can exploit this, via a specially crafted web page, to disclose memory contents. (CVE-2015-2712)
• A use-after-free error exists due to improper processing of text when vertical text is enabled. A remote attacker can exploit this to dereference already freed memory. (CVE-2015-2713) - A use-after-free error exists in the ‘RegisterCurrentThread()’ function in ‘nsThreadManager.cpp’ due to a race condition related to media decoder threads created during the shutdown process. A remote attacker can exploit this to dereference already freed memory. (CVE-2015-2715)
• A buffer overflow condition exists in the ‘XML_GetBuffer()’ function in xmlparse.c due to improper validation of user-supplied input when handling compressed XML content. An attacker can exploit this to cause a buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-2716)
• An integer overflow condition exists in the ‘parseChunk()’ function in ‘MPEG4Extractor.cpp’ due to improper handling of MP4 video metadata in chunks. A remote attacker can exploit this, via specially crafted media content, to cause a heap-based buffer overflow, resulting in the execution of arbitrary code. (CVE-2015-2717)
• A security bypass vulnerability exists in ‘WebChannel.jsm’ due to improper handling of message traffic. An untrusted page hosting a trusted page within an iframe can intercept webchannel responses for the trusted page. This allows a remote attacker, via a specially crafted web page, to bypass origin restrictions, resulting in the disclosure of sensitive information. (CVE-2015-2718)
• Multiple integer overflow conditions exist in the bundled libstagefright component due to improper validation of user-supplied input when processing MPEG4 sample metadata. A remote attacker can exploit this, via specially crafted media content, to execute arbitrary code. (CVE-2015-4496)
