Security Vulnerabilities
Issue summary: The 'openssl dgst' command-line tool silently truncates input
data to 16MB when using one-shot signing algorithms and reports success instead
of an error.
Impact summary: A user signing or verifying files larger than 16MB with
one-shot algorithms (such as Ed25519, Ed448, or ML-DSA) may believe the entire
file is authenticated while trailing data beyond 16MB remains unauthenticated.
When the 'openssl dgst' command is used with algorithms that only support
one-shot signing (Ed25519, Ed448, ML-DSA-44, ML-DSA-65, ML-DSA-87), the input
is buffered with a 16MB limit. If the input exceeds this limit, the tool
silently truncates to the first 16MB and continues without signaling an error,
contrary to what the documentation states. This creates an integrity gap where
trailing bytes can be modified without detection if both signing and
verification are performed using the same affected codepath.
The issue affects only the command-line tool behavior. Verifiers that process
the full message using library APIs will reject the signature, so the risk
primarily affects workflows that both sign and verify with the affected
'openssl dgst' command. Streaming digest algorithms for 'openssl dgst' and
library users are unaffected.
The FIPS modules in 3.5 and 3.6 are not affected by this issue, as the
command-line tools are outside the OpenSSL FIPS module boundary.
OpenSSL 3.5 and 3.6 are vulnerable to this issue.
OpenSSL 3.4, 3.3, 3.0, 1.1.1 and 1.0.2 are not affected by this issue.

The function _ux_host_class_storage_media_mount() is responsible for mounting partitions on a USB mass storage device. When it encounters an extended partition entry in the partition table, it recursively calls itself to mount the next logical partition.
This recursion occurs in _ux_host_class_storage_partition_read(), which parses up to four partition entries. If an extended partition is found (with type UX_HOST_CLASS_STORAGE_PARTITION_EXTENDED or EXTENDED_LBA_MAPPED), the code invokes:
_ux_host_class_storage_media_mount(storage, sector + _ux_utility_long_get(...));
There is no limit on the recursion depth or tracking of visited sectors. As a result, a malicious or malformed disk image can include cyclic or excessively deep chains of extended partitions, causing the function to recurse until stack overflow occurs.

LibreNMS 1.46 contains an authenticated SQL injection vulnerability in the MAC accounting graph endpoint that allows remote attackers to extract database information. Attackers can exploit the vulnerability by manipulating the 'sort' parameter with crafted SQL injection techniques to retrieve sensitive database contents through time-based blind SQL injection.

TapinRadio 2.13.7 contains a denial of service vulnerability in the application proxy settings that allows attackers to crash the program by overflowing input fields. Attackers can paste a large buffer of 20,000 characters into the username and address fields to cause the application to become unresponsive and require reinstallation.

Knockpy 4.1.1 contains a CSV injection vulnerability that allows attackers to inject malicious formulas into CSV reports through unfiltered server headers. Attackers can manipulate server response headers to include spreadsheet formulas that will execute when the CSV is opened in spreadsheet applications.

n8n contains a critical Remote Code Execution (RCE) vulnerability in its workflow Expression evaluation system. Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime.
An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of workflows, and execution of system-level operations.
