Mozilla Foundation Security Advisory 2022-13
Security Vulnerabilities fixed in Firefox 99
Announced: April 5, 2022
Impact: high
Products: Firefox
Fixed in: Firefox 99
# 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.

o Bug 1745667
# CVE-2022-28281: Out of bounds write due to unexpected WebAuthN Extensions
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.
References
o Bug 1755621
# CVE-2022-28282: Use-after-free in DocumentL10n::TranslateDocument
Reporter: Kirin
Impact: moderate
Description
By using a link with rel="localization" a use-after-free could have been
triggered by destroying an object during JavaScript execution and then
referencing the object through a freed pointer, leading to a potentially
exploitable crash.

o Bug 1751609
# 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.
References
o Bug 1754066
# 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.

o Bug 1754522
# CVE-2022-28285: Incorrect AliasSet used in JIT Codegen
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.

o Bug 1756957
# CVE-2022-28286: iframe contents could be rendered outside the border
Reporter: prada960808
Impact: low
Description
Due to a layout change, iframe contents could have been rendered outside of its
border. This could have led to user confusion or spoofing attacks.

o Bug 1735265
# CVE-2022-28287: Text Selection could crash Firefox
Reporter: Aryan Sinha
Impact: low
Description
In unusual circumstances, selecting text could cause text selection caching to
behave incorrectly, leading to a crash.

o Bug 1741515
# 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.
