It is, therefore, affected by multiple vulnerabilities : - Multiple memory corruption issues exist that allow an unauthenticated, remote attacker to execute arbitrary code by convincing a user to visit a specially crafted website. (CVE-2017-5470) - A use-after-free error exists in the EndUpdate() function in nsCSSFrameConstructor.cpp that is triggered when reconstructing trees during regeneration of CSS layouts. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-5472) - A use-after-free error exists in the Reload() function in nsDocShell.cpp that is triggered when using an incorrect URL during the reload of a docshell. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7749) - A use-after-free error exists in the Hide() function in nsDocumentViewer.cpp that is triggered when handling track elements. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7750) - A use-after-free error exists in the nsDocumentViewer class in nsDocumentViewer.cpp that is triggered when handling content viewer listeners. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7751) - A use-after-free error exists that is triggered when handling events while specific user interaction occurs with the input method editor (IME). An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7752) - An out-of-bounds read error exists in the IsComplete() function in WebGLTexture.cpp that is triggered when handling textures. An unauthenticated, remote attacker can exploit this to disclose memory contents. (CVE-2017-7754) - A privilege escalation vulnerability exists due to improper loading of dynamic-link library (DLL) files. A local attacker can exploit this, via a specially crafted DLL file in the installation path, to inject and execute arbitrary code. (CVE-2017-7755) - A use-after-free error exists in the SetRequestHead() function in XMLHttpRequestMainThread.cpp that is triggered when logging XML HTTP Requests (XHR). An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7756) - A use-after-free error exists in ActorsParent.cpp due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7757) - An out-of-bounds read error exists in the AppendAudioSegment() function in TrackEncoder.cpp that is triggered when the number of channels in an audio stream changes while the Opus encoder is in use. An unauthenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2017-7758) - A flaw exists in the NS_main() function in updater.cpp due to improper validation of input when handling callback file path parameters. A local attacker can exploit this to manipulate files in the installation directory. (CVE-2017-7760) - A flaw exists in the Maintenance Service helper.exe application that is triggered as permissions for a temporary directory are set to writable by non-privileged users. A local attacker can exploit this to delete arbitrary files on the system. (CVE-2017-7761) - A flaw exists in the isLabelSafe() function in nsIDNService.cpp that is triggered when handling characters from different unicode blocks. An unauthenticated, remote attacker can exploit this, via a specially crafted IDN domain, to spoof a valid URL and conduct phishing attacks. (CVE-2017-7764) - A flaw exists that is triggered due to improper parsing of long filenames when handling downloaded files.
