VCID-16cw-k8f1-8kc4 Mozilla developers and community members Julien Cristau, Christian Holler reported memory safety bugs present in Firefox 92. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. CVE-2021-38499
VCID-1rj3-tt63-4yc1 Through use of reportValidity() and window.open(), a plain-text validation message could have been overlaid on another origin, leading to possible user confusion and spoofing attacks. CVE-2021-38497
VCID-2k99-39yt-gkbe During operations on MessageTasks, a task may have been removed while it was still scheduled, resulting in memory corruption and a potentially exploitable crash. CVE-2021-38496
VCID-6fkp-5fzu-fydp Mozilla developers and community members Andreas Pehrson and Christian Holler reported memory safety bugs present in Thunderbird 91.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. CVE-2021-38500
VCID-9y48-sjn7-rqeu Mozilla developers and community members Kevin Brosnan, Mihai Alexandru Michis, and Christian Holler reported memory safety bugs present in Thunderbird 91.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. CVE-2021-38501
VCID-hhu1-cgcx-nfev During process shutdown, a document could have caused a use-after-free of a languages service object, leading to memory corruption and a potentially exploitable crash. CVE-2021-38498
VCID-khsw-jwtm-8faq A use-after-free could have occurred when an HTTP2 session object was released on a different thread, leading to memory corruption and a potentially exploitable crash. CVE-2021-43535
VCID-vtjf-sufh-p3h4 crossbeam-deque Data Race before v0.7.4 and v0.8.1 ### Impact In the affected version of this crate, the result of the race condition is that one or more tasks in the worker queue can be popped twice instead of other tasks that are forgotten and never popped. If tasks are allocated on the heap, this can cause double free and a memory leak. If not, this still can cause a logical bug. Crates using `Stealer::steal`, `Stealer::steal_batch`, or `Stealer::steal_batch_and_pop` are affected by this issue. ### Patches This has been fixed in crossbeam-deque 0.8.1 and 0.7.4. ### Credits This issue was reported and fixed by Maor Kleinberger. ### License This advisory is in the public domain. CVE-2021-32810
