Impact
high
Description

An attacker could have leveraged the Windows Error Reporter to run arbitrary code on the system escaping the sandbox. Note: This issue only affected Windows operating systems. Other operating systems are unaffected.

#CVE-2024-2616: Improve handling of out-of-memory conditions in ICU

Reporter
Ryan VanderMeulen and Dan Minor
Impact
high
Description

To harden ICU against exploitation, the behavior for out-of-memory conditions was changed to crash instead of attempt to continue.

#CVE-2023-5388: NSS susceptible to timing attack against RSA decryption

Reporter
Hubert Kario
Impact
moderate
Description

NSS was susceptible to a timing side-channel attack when performing RSA decryption. This attack could potentially allow an attacker to recover the private data.

#CVE-2024-2612: Self referencing object could have potentially led to a use-after-free

Reporter
Ronald Crane
Impact
moderate
Description

If an attacker could find a way to trigger a particular code path in SafeRefPtr, it could have triggered a crash or potentially be leveraged to achieve code execution.

#CVE-2024-2614: Memory safety bugs fixed in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9

Reporter
Noah Lokocz, Kevin Brosnan, Ryan VanderMeulen and the Mozilla Fuzzing Team
Impact
high
Description

Memory safety bugs present in Firefox 123, Firefox ESR 115.8, and Thunderbird 115.8. 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.
