USN-3260-1 fixed vulnerabilities in Firefox. The update caused the date picker panel and form validation errors to close immediately on opening. This update fixes the problem.

We apologize for the inconvenience.

Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit these to read uninitialized memory, obtain sensitive information, spoof the addressbar contents or other UI elements, escape the sandbox to read local files, conduct cross-site scripting (XSS) attacks, cause a denial of service via application crash, or execute arbitrary code. (CVE-2017-5429, CVE-2017-5430, CVE-2017-5432, CVE-2017-5433, CVE-2017-5434, CVE-2017-5435, CVE-2017-5436, CVE-2017-5437, CVE-2017-5438, CVE-2017-5439, CVE-2017-5440, CVE-2017-5441, CVE-2017-5442, CVE-2017-5443, CVE-2017-5444, CVE-2017-5445, CVE-2017-5446, CVE-2017-5447, CVE-2017-5448, CVE-2017-5449, CVE-2017-5451, CVE-2017-5453, CVE-2017-5454, CVE-2017-5455, CVE-2017-5456, CVE-2017-5458, CVE-2017-5459, CVE-2017-5460, CVE-2017-5461, CVE-2017-5464, CVE-2017-5465, CVE-2017-5466, CVE-2017-5467, CVE-2017-5468, CVE-2017-5469)

  - A use-after-free error exists in the SMIL animation     functions when handling animation elements. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5433)

  - A use-after-free error exists when redirecting focus     handling that allows an unauthenticated, remote attacker     to cause a denial of service condition or the execution     of arbitrary code. (CVE-2017-5434)

  - A use-after-free error exists in design mode     interactions when handling transaction processing in     the editor. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-5435)

  - An out-of-bounds write error exists in the Graphite 2     library when handling specially crafted Graphite fonts.
    An unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5436)

  - A use-after-free error exists in the nsAutoPtr()     function during XSLT processing due to the result     handler being held by a freed handler. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5438)

  - A use-after-free error exists in the Length() function     in nsTArray when handling template parameters during     XSLT processing. An unauthenticated, remote attacker can     exploit this to cause a denial of service condition or     the execution of arbitrary code. (CVE-2017-5439)

  - A use-after-free error exists in the txExecutionState     destructor when processing XSLT content. An     unauthenticated, remote attacker can exploit this to     cause a denial of service condition or the execution of     arbitrary code. (CVE-2017-5440)

  - A use-after-free error exists when holding a selection     during scroll events. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2017-5441)

  - A use-after-free error exists when changing styles in     DOM elements that allows an unauthenticated, remote     attacker to cause a denial of service condition or the     execution of arbitrary code. (CVE-2017-5442)

  - An out-of-bounds write error exists while decoding     improperly formed BinHex format archives that allows an     unauthenticated, remote attacker to cause a denial of     service condition or the execution of arbitrary code.
    (CVE-2017-5443)

  - A buffer overflow condition exists while parsing     application/http-index-format format content due to     improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this, via     improperly formatted data, to disclose out-of-bounds     memory content. (CVE-2017-5444)

  - A flaw exists in nsDirIndexParser.cpp when parsing     application/http-index-format format content in which     uninitialized values are used to create an array. An     unauthenticated, remote attacker can exploit this to     disclose memory contents. (CVE-2017-5445)

  - An out-of-bounds read error exists when handling HTTP/2     DATA connections to a server that sends DATA frames with     incorrect content. An unauthenticated, remote attacker     can exploit to cause a denial of service condition or     the disclosure of memory contents. (CVE-2017-5446)

  - An out-of-bounds read error exists when processing glyph     widths during text layout. An unauthenticated, remote     attacker can exploit this to cause a denial of service     condition or the disclosure of memory contents.
    (CVE-2017-5447)

  - An out-of-bounds write error exists in the     ClearKeyDecryptor::Decrypt() function within file     ClearKeyDecryptionManager.cpp when decrypting     Clearkey-encrypted media content. An unauthenticated,     remote attacker can exploit this to cause a denial of     service condition or the execution of arbitrary code.
    This vulnerability can only be exploited if a secondary     mechanism can be used to escape the Gecko Media Plugin     (GMP) sandbox. (CVE-2017-5448)

  - A flaw exists when handling bidirectional Unicode text     in conjunction with CSS animations that allows an     unauthenticated, remote attacker to cause a denial of     service condition or the execution or arbitrary code.
    (CVE-2017-5449)

  - A flaw exists in the handling of specially crafted     'onblur' events. An unauthenticated, remote attacker can     exploit this, via a specially crafted event, to spoof     the address bar, making the loaded site appear to be     different from the one actually loaded. (CVE-2017-5451)

  - A flaw exists in the RSS reader preview page due to     improper sanitization of URL parameters for a feed's     TITLE element. An unauthenticated, remote attacker can     exploit this to spoof the TITLE element. However, no     scripted content can be run. (CVE-2017-5453)

  - A flaw exists in the FileSystemSecurity::Forget()     function within file FileSystemSecurity.cpp when using     the File Picker due to improper sanitization of input     containing path traversal sequences.
