Mozilla Firefox ESR < 52.1 Multiple Vulnerabilities

Versions of Mozilla Firefox ESR earlier than 52.1 are unpatched for the following vulnerabilities :

• A use-after-free error exists that is related to certain text input selections. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5432)
• A use-after-free error exists in the SMIL animation functions. The issue is triggered when handling animation elements. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5433)
• A use-after-free error exists that is triggered when redirecting focus handling. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5434)
• A use-after-free error exists that is triggered when processing transactions in the editor during design mode interactions. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5435)
• A use-after-free error exists in the ‘nsAutoPtr()’ function that is triggered during XSLT processing. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5438)
• A use-after-free error exists in the ‘Length()’ function in ‘nsTArray’ that is triggered when handling template parameters during XSLT processing. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5439)
• A use-after-free error exists in the ‘txExecutionState’ destructor that is triggered during the processing of XSLT content. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5440)
• A use-after-free error exists that is triggered when holding a selection during scroll events. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5441)
• A use-after-free error exists that is triggered when changing styles in DOM elements. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5442)
• An out-of-bounds write flaw exists that is triggered during the decoding of improperly formed BinHex format archives. This may allow a context-dependent attacker to potentially execute arbitrary code. (CVE-2017-5443)
• An overflow condition exists that is triggered as certain input is not properly validated when parsing ‘application/http-index-format’ content. This may allow a context-dependent attacker to cause a buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2017-5444)
• An out-of-bounds read flaw exists that is triggered when handling ‘HTTP/2 DATA’ connections that send DATA frames with incorrect data content. This may allow a context-dependent attacker to potentially disclose memory contents. (CVE-2017-5446)
• An out-of-bounds read flaw exists that is triggered when processing glyph widths during text layouts. This may allow a context-dependent attacker to potentially disclose memory contents. (CVE-2017-5447)
• An out-of-bounds write flaw exists in the ‘ClearKeyDecryptor::Decrypt()’ function in ‘ClearKeyDecryptionManager.cpp’ that is triggered when decrypting Clearkey-encrypted media content. This may allow a context-dependent attacker to potentially execute arbitrary code. (CVE-2017-5448)
• An overflow condition exists in WebGL. The issue is triggered as certain input is not properly validated when handling web content. This may allow a context-dependent attacker to cause a buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2017-5459)
• A use-after-free error exists in frame selection that is triggered when handling a combination of malicious script content and key presses. This may allow a context-dependent attacker to dereference already freed memory and potentially execute arbitrary code. (CVE-2017-5460)
• An overflow condition exists in Base64 decoding. The issue is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a buffer overflow, resulting in a denial of service or potentially allowing the execution of arbitrary code. (CVE-2017-5461)
• A flaw in the DRBG number generation exists that is triggered as internal state V does not correctly carry bits over. This may result in potentially predictable random number generation. (CVE-2017-5462)
• A flaw exists that is triggered as certain input is not properly validated when making changes to DOM content in the accessibility tree. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. (CVE-2017-5464)
• An out-of-bounds read flaw exists in ‘ConvolvePixel’ that is triggered when processing specially crafted SVG content. This may allow a context-dependent attacker to potentially disclose memory contents. (CVE-2017-5465)
• Multiple overflow conditions exist in the FLEX generated code. The issue is triggered as certain input is not properly validated. This may allow a context-dependent attacker to cause a buffer overflow, potentially allowing the execution of arbitrary code. (CVE-2017-5469)
• Multiple unspecified flaws exist that are triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code. (CVE-2017-5429 ,CVE-2017-5430)
