#CVE-2022-1097: Use-after-free in NSSToken objects
Reporter
Randell Jesup
Impact
high
Description
NSSToken objects were referenced via direct points, and could have been accessed in an unsafe way on different threads, leading to a use-after-free and potentially exploitable crash.

Reporter
Axel ‘0vercl0k’ Souchet
Impact
high
Description
If a compromised content process sent an unexpected number of WebAuthN Extensions in a Register command to the parent process, an out of bounds write would have occurred leading to memory corruption and a potentially exploitable crash.

#CVE-2022-28283: Missing security checks for fetching sourceMapURL
Reporter
Gijs
Impact
moderate
Description
The sourceMapURL feature in devtools was missing security checks that would have allowed a webpage to attempt to include local files or other files that should have been inaccessible.

#CVE-2022-28284: Script could be executed via svg’s use element
Reporter
Leo Balter
Impact
moderate
Description
SVG’s <use> element could have been used to load unexpected content that could have executed script in certain circumstances. While the specification seems to allow this, other browsers do not, and web developers relied on this property for script security so gecko’s implementation was aligned with theirs.

Reporter
Lukas Bernhard
Impact
moderate
Description
When generating the assembly code for MLoadTypedArrayElementHole, an incorrect AliasSet was used. In conjunction with another vulnerability this could have been used for an out of bounds memory read.

#CVE-2022-24713: Denial of Service via complex regular expressions
Reporter
Addison Crump and Jan-Erik Rediger
Impact
low
Description
The rust regex crate did not properly prevent crafted regular expressions from taking an arbitrary amount of time during parsing. If an attacker was able to supply input to this crate, they could have caused a denial of service in the browser.

#CVE-2022-28289: Memory safety bugs fixed in Firefox 99 and Firefox ESR 91.8
Reporter
Mozilla developers
Impact
high
Description
Mozilla developers and community members Nika Layzell, Andrew McCreight, Gabriele Svelto, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 98 and Firefox ESR 91.7. 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.

As a Technical Account Manager (TAM) one of the best parts of the job is the regular contact with our customers, talking to them frequently and helping them solve interesting problems. One of our customers came to me with an interesting challenge. The team creates a new Gold Image every month and they wanted to provide release notes for the image, automatically generating a list of CVEs that had been fixed in this version of the image.
regex is an implementation of regular expressions for the Rust language. The regex crate features built-in mitigations to prevent denial of service attacks caused by untrusted regexes, or untrusted input matched by trusted regexes. Those (tunable) mitigations already provide sane defaults to prevent attacks. This guarantee is documented and it's considered part of the crate's API. Unfortunately a bug was discovered in the mitigations designed to prevent untrusted regexes to take an arbitrary amount of time during parsing, and it's possible to craft regexes that bypass such mitigations. This makes it possible to perform denial of service attacks by sending specially crafted regexes to services accepting user-controlled, untrusted regexes. All versions of the regex crate before or equal to 1.5.4 are affected by this issue. The fix is include starting from regex 1.5.5. All users accepting user-controlled regexes are recommended to upgrade immediately to the latest version of the regex cra...
