#CVE-2024-2607: JIT code failed to save return registers on Armv7-A

Reporter
Gary Kwong
Impact
high
Description

Return registers were overwritten which could have allowed an attacker to execute arbitrary code. Note: This issue only affected Armv7-A systems. Other operating systems are unaffected.

#CVE-2024-2608: Integer overflow could have led to out of bounds write

Reporter
Ronald Crane
Impact
high
Description

AppendEncodedAttributeValue(), ExtraSpaceNeededForAttrEncoding() and AppendEncodedCharacters() could have experienced integer overflows, causing underallocation of an output buffer leading to an out of bounds write.

#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-2024-2609: Permission prompt input delay could expire when not in focus

Reporter
Shaheen Fazim
Impact
moderate
Description

The permission prompt input delay could have expired while the window is not in focus, which made the prompt vulnerable to clickjacking by malicious websites.

Impact
moderate
Description

#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-2024-2613: Improper handling of QUIC ACK frame data could have led to OOM

Reporter
Max Inden
Impact
low
Description

Data was not properly sanitized when decoding a QUIC ACK frame; this could have led to unrestricted memory consumption and a crash.

#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.

Reporter
Paul Bone and the Mozilla Fuzzing Team
Impact
critical
Description

Memory safety bugs present in Firefox 123. 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.
