Versions of Mozilla Thunderbird prior to 38.4 are outdated and thus unpatched for the following vulnerabilities :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