The update implementation in Mozilla Firefox before 38.0 on Windows does not ensure that the pathname for updater.exe corresponds to the application directory, which might allow local users to gain privileges via a Trojan horse file.

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)

Versions of Mozilla Firefox earlier than 38.0 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)

 - 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)
