Title
Junos OS and Junos OS Evolved: An Unchecked Return Value in multiple users interfaces affects confidentiality and integrity of device operations
Summary
An Unchecked Return Value vulnerability in the user interfaces to the Juniper Networks Junos OS and Junos OS Evolved, the CLI, the XML API, the XML Management Protocol, the NETCONF Management Protocol, the gNMI interfaces, and the J-Web User Interfaces causes unintended effects such as demotion or elevation of privileges associated with an operators actions to occur.
Multiple scenarios may occur; for example: privilege escalation over the device or another account, access to files that should not otherwise be accessible, files not being accessible where they should be accessible, code expected to run as non-root may run as root, and so forth.
This issue affects:
Juniper Networks Junos OS
* All versions prior to 20.4R3-S7;
* 21.1 versions prior to 21.1R3-S5;
* 21.2 versions prior to 21.2R3-S5;
* 21.3 versions prior to 21.3R3-S4;
* 21.4 versions prior to 21.4R3-S3;
* 22.1 versions prior to 22.1R3-S2;
* 22.2 versions prior to 22.2R2-S2, 22.2R3;
* 22.3 versions prior to 22.3R1-S2, 22.3R2.
Juniper Networks Junos OS Evolved
* All versions prior to 21.4R3-S3-EVO;
* 22.1-EVO version 22.1R1-EVO and later versions prior to 22.2R2-S2-EVO, 22.2R3-EVO;
* 22.3-EVO versions prior to 22.3R1-S2-EVO, 22.3R2-EVO.

CVE-2023-37902 (GCVE-0-2023-37902)

Title
Vyper's ecrecover can return undefined data if signature does not verify
Summary
Vyper is a Pythonic programming language that targets the Ethereum Virtual Machine (EVM). Prior to version 0.3.10, the ecrecover precompile does not fill the output buffer if the signature does not verify. However, the ecrecover builtin will still return whatever is at memory location 0. This means that the if the compiler has been convinced to write to the 0 memory location with specially crafted data (generally, this can happen with a hashmap access or immutable read) just before the ecrecover, a signature check might pass on an invalid signature. Version 0.3.10 contains a patch for this issue.

Title
RIOT-OS vulnerable to NULL pointer dereference in gnrc_pktbuf_mark
Summary
RIOT-OS, an operating system for Internet of Things (IoT) devices, contains a network stack with the ability to process 6LoWPAN frames. Prior to version 2023.04, an attacker can send a crafted frame to the device to trigger a NULL pointer dereference leading to denial of service. This issue is fixed in version 2023.04. There are no known workarounds.

Title
Libssh: missing checks for return values for digests
Summary
A flaw was found in the libssh implements abstract layer for message digest (MD) operations implemented by different supported crypto backends. The return values from these were not properly checked, which could cause low-memory situations failures, NULL dereferences, crashes, or usage of the uninitialized memory as an input for the KDF. In this case, non-matching keys will result in decryption/integrity failures, terminating the connection.

Title
Segmentation fault in Brocade Fabric OS after Brocade Fabric OS v9.0
Summary
A
segmentation fault can occur in Brocade Fabric OS after Brocade Fabric
OS v9.0 and before Brocade Fabric OS v9.2.0a through the passwdcfg
command. This
could allow an authenticated privileged user local user to crash a
Brocade Fabric OS swith using the cli “passwdcfg --set -expire
-minDiff“.

Title
Missing error check and insufficient random bytes in HTTP Digest authentication for SOAP
Summary
In PHP versions 8.0.* before 8.0.29, 8.1.* before 8.1.20, 8.2.* before 8.2.7 when using SOAP HTTP Digest Authentication, random value generator was not checked for failure, and was using narrower range of values than it should have. In case of random generator failure, it could lead to a disclosure of 31 bits of uninitialized memory from the client to the server, and it also made easier to a malicious server to guess the client's nonce.

Mitigation MIT-53
Implementation
Check the results of all functions that return a value and verify that the value is expected.
Mitigation MIT-56
Implementation
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Implementation
Ensure that you account for all possible return values from the function.
Mitigation
Implementation
When designing a function, make sure you return a value or throw an exception in case of an error.
