  script_tag(name:"insight", value:"CVE-2019-9790: Use-after-free when removing in-use DOM elements
A use-after-free vulnerability can occur when a raw pointer to a DOM element on a page is obtained using JavaScript and the element is then removed while still in use. This results in a potentially exploitable crash.

CVE-2019-9791: Type inference is incorrect for constructors entered through on-stack replacement with IonMonkey
The type inference system allows the compilation of functions that can cause type confusions between arbitrary objects when compiled through the IonMonkey just-in-time (JIT) compiler and when the constructor function is entered through on-stack replacement (OSR). This allows for possible arbitrary reading and writing of objects during an exploitable crash.

CVE-2019-9792: IonMonkey leaks JS_OPTIMIZED_OUT magic value to script
The IonMonkey just-in-time (JIT) compiler can leak an internal JS_OPTIMIZED_OUT magic value to the running script during a bailout. This magic value can then be used by JavaScript to achieve memory corruption, which results in a potentially exploitable crash.

CVE-2019-9793: Improper bounds checks when Spectre mitigations are disabled
A mechanism was discovered that removes some bounds checking for string, array, or typed array accesses if Spectre mitigations have been disabled. This vulnerability could allow an attacker to create an arbitrary value in compiled JavaScript, for which the range analysis will infer a fully controlled, incorrect range in circumstances where users have explicitly disabled Spectre mitigations. Note: Spectre mitigations are currently enabled for all users by default settings.

CVE-2019-9795: Type-confusion in IonMonkey JIT compiler
A vulnerability where type-confusion in the IonMonkey just-in-time (JIT) compiler could potentially be used by malicious JavaScript to trigger a potentially exploitable crash.

CVE-2019-9796: Use-after-free with SMIL animation controller
A use-after-free vulnerability can occur when the SMIL animation controller incorrectly registers with the refresh driver twice when only a single registration is expected. When a registration is later freed with the removal of the animation controller element, the refresh driver incorrectly leaves a dangling pointer to the driver's observer array.

CVE-2019-9797: Cross-origin theft of images ... [Please see the references for more information on the vulnerabilities]");
