Versions of Mozilla Thunderbird prior to 38.4 are outdated and thus unpatched for the following vulnerabilities :

 - Multiple memory corruption issues exist due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these issues, via a specially crafted web page, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-4513, CVE-2015-4514)
 - An unspecified use-after-poison flaw exists in the 'sec_asn1d_parse_leaf()' function in Mozilla Network Security Services (NSS) due to improper restriction of access to an unspecified data structure. A remote attacker can exploit this, via crafted OCTET STRING data, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-7181)
 - A heap buffer overflow condition exists in the ASN.1 decoder in Mozilla Network Security Services (NSS) due to improper validation of user-supplied input. A remote attacker can exploit this, via crafted OCTET STRING data, to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-7182)
 - An integer overflow condition exists in the 'PL_ARENA_ALLOCATE' macro in the Netscape Portable Runtime (NSPR) due to improper validation of user-supplied input. A remote attacker can exploit this to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-7183)
 - A same-origin bypass vulnerability exists due to improper handling of trailing whitespaces in the IP address hostname. A remote attacker can exploit this, by appending whitespace characters to an IP address string, to bypass the same-origin policy and conduct a cross-site scripting attack. (CVE-2015-7188)
 - A race condition exists in the 'JPEGEncoder()' function due to improper validation of user-supplied input when handling canvas elements. A remote attacker can exploit this to cause a heap-based buffer overflow, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-7189)
 - A cross-origin resource sharing (CORS) request bypass vulnerability exists due to improper implementation of the CORS cross-origin request algorithm for the POST method in situations involving an unspecified Content-Type header manipulation. A remote attacker can exploit this to perform a simple request instead of a 'preflight' request. (CVE-2015-7193)
 - A buffer underflow condition exists in libjar due to improper validation of user-supplied input when handling ZIP archives. A remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-7194)
 - A security bypass vulnerability exists due to improperly controlling the ability of a web worker to create a WebSocket object in the 'WebSocketImpl::Init()' method. A remote attacker can exploit this to bypass intended mixed-content restrictions. (CVE-2015-7197)
 - A buffer overflow condition exists in 'TextureStorage11' in ANGLE due to improper validation of user-supplied input. A remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2015-7198)
 - A flaw exists in the 'AddWeightedPathSegLists()' function due to missing return value checks during SVG rendering. A remote attacker can exploit this, via a crafted SVG document, to corrupt memory, resulting in a denial of service condition or the execution of arbitrary code. (CVE-2015-7199)
 - A flaw exists in the CryptoKey interface implementation due to missing status checks. A remote attacker can exploit this to make changes to cryptographic keys and execute arbitrary code. (CVE-2015-7200)

The version of Mozilla Firefox is prior to 42.0 and is affected by multiple vulnerabilities : 

 - Multiple flaws in the browser engine allow remote attackers to corrupt memory and potentially execute arbitrary code. (CVE-2015-4513, CVE-2015-4514)
 - A flaw exists that is triggered when handling type 3 messages as part of the NTLM authentication exchange. This may allow an attacker to disclose system hostname and windows domain information. (CVE-2015-4515)
 - A flaw exists related to the whitelist used by Reader View to disable script for rendered pages being too permissive. This may allow an attacker to bypass CSP protections and in turn potentially conduct XSS attacks. (CVE-2015-4518)
 - An unspecified use-after-poison flaw exists in Mozilla Network Security Services (NSS) in the 'sec_asn1d_parse_leaf()' function that may allow an attacker to execute arbitrary code. (CVE-2015-7181)
 - An overflow condition exists in Mozilla Network Security Services (NSS) in the ASN.1 decoder. The issue is triggered as user-supplied input is not properly validated when handling an OCTET STRING. This may allow an attacker to cause a heap-based buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2015-7182)
 - An integer overflow condition exists in Netscape Portable Runtime (NSPR) in the PL_ARENA_ALLOCATE macro that is triggered as user-supplied input is not properly validated during memory allocation. This may allow an attacker to corrupt memory, crashing an application linked against the library or potentially allowing the execution of arbitrary code. (CVE-2015-7183)
 - A flaw exists in the 'fetch()' API that is due it failing to properly implement the Cross-Origin Resource Sharing (CORS) feature. This may allow an attacker to potentially gain unauthorized access to cross-origin information. (CVE-2015-7184)- A flaw exists that is due to the program failing to enforce settings when disabling scripts in the Add-on SDK panel. By defining a panel with "script: false", all script execution is designed to be disabled. With a crafted web site, an attacker may be able to bypass this restriction, facilitating scripting attacks. (CVE-2015-7187)
 - A flaw exists in 'netwerk/base/nsStandardURL.cpp' that is triggered during the handling of trailing whitespaces in the IP address hostname. This may allow an attacker to bypass the same-origin policy. (CVE-2015-7188)
 - A race condition exists in the 'JPEGEncoder()' function. The issue is triggered as user-supplied input is not properly validated when handling canvas elements. This may allow an attacker to cause a heap-based buffer overflow and potentially execute arbitrary code. (CVE-2015-7189)
 - A flaw exists (Firefox for OS X only) in the 'ConvertToNSArray()' function in 'accessible/mac/mozAccessible.mm.' The issue is triggered when an accessibility tool requests the index of a table row via the 'NSAccessibilityIndexAttribute' value. This may allow an attacker to potentially execute arbitrary code. (CVE-2015-7192)
 - A flaw exists that is triggered during the handling of content-type headers for multiple media types returned from a server. This may allow an attacker to bypass cross-origin resource sharing (CORS) and perform simple request instead of a 'preflight' request. (CVE-2015-7193)
 - A flaw exists in the 'nsZipArchive::GetData()' function in 'modules/libjar/nsZipArchive.cpp' that is triggered as user-supplied input is not properly validated when handling ZIP archives. This may allow an attacker to corrupt memory and potentially execute arbitrary code. (CVE-2015-7194)
 - A flaw exists that is triggered during the parsing of escaped characters in the hostname of location headers. This may allow an attacker to gain access to arbitrary site-specific token information. (CVE-2015-7195)
 - A flaw exists in the '_releaseobject()' function in 'dom/plugins/base/nsNPAPIPlugin.cpp' that is triggered when JavaScript wrappers become deallocated during use. This may allow an attacker to corrupt memory and potentially execute arbitrary code. (CVE-2015-7196)
 - A flaw exists in the 'WebSocketImpl::Init()' function in 'dom/base/WebSocket.cpp' that is triggered when determining the origin of the entry settings object for workers. This may allow an attacker to bypass the mixed content WebSocket policy. (CVE-2015-7197)
 - An overflow condition exists in the 'WebGLTexture::EnsureInitializedImageData()' function in 'dom/canvas/WebGLTexture.cpp.' The issue is triggered as user-supplied input is not properly validated. This may allow an attacker to cause a buffer overflow and potentially execute arbitrary code. (CVE-2015-7198)
 - A flaw exists in 'dom/svg/SVGPathSegListSMILType.cpp' related to missing return value checks for the 'AddWeightedPathSegLists()' function during SVG rendering. This may allow an attacker to corrupt memory and execute arbitrary code. (CVE-2015-7199)
 - A flaw exists that is due to missing status checks in CryptoKey related to OOM (Out-of-Memory) conditions. This may allow an attacker to make changes to crpytographic keys and potentially execute arbitrary code. (CVE-2015-7200)
