  script_tag(name:"insight", value:"CVE-2019-11756: Use-after-free of SFTKSession object
Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service).

CVE-2019-17008: Use-after-free in worker destruction
When using nested workers, a use-after-free could occur during worker destruction. This resulted in a potentially exploitable crash.

CVE-2019-11745: Out of bounds write in NSS when encrypting with a block cipher
When encrypting with a block cipher, if a call to NSC_EncryptUpdate was made with data smaller than the block size, a small out of bounds write could occur. This could have caused heap corruption and a potentially exploitable crash.

CVE-2019-17014: Dragging and dropping a cross-origin resource, incorrectly loaded as an image, could result in information disclosure
If an image had not loaded correctly (such as when it is not actually an image), it could be dragged and dropped cross-domain, resulting in a cross-origin information leak.

CVE-2019-17010: Use-after-free when performing device orientation checks
Under certain conditions, when checking the Resist Fingerprinting preference during device orientation checks, a race condition could have caused a use-after-free and a potentially exploitable crash.

CVE-2019-17005: Buffer overflow in plain text serializer
The plain text serializer used a fixed-size array for the number of elements it could process, however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash.

CVE-2019-17011: Use-after-free when retrieving a document in antitracking
Under certain conditions, when retrieving a document from a DocShell in the antitracking code, a race condition could cause a use-after-free condition and a potentially exploitable crash.

CVE-2019-17012: Memory safety bugs fixed in Firefox 71 and Firefox ESR 68.3
Mozilla developers Christoph Diehl, Nathan Froyd, Jason Kratzer, Christian Holler, Karl Tomlinson, Tyson Smith reported memory safety bugs present in Firefox 70 and Firefox ESR 68.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these ... [Please see the references for more information on the vulnerabilities]");
