#ssh

A new Golang-based peer-to-peer (P2P) botnet has been spotted actively targeting Linux servers in the education sector since its emergence in March 2022. Dubbed Panchan by Akamai Security Research, the malware "utilizes its built-in concurrency features to maximize spreadability and execute malware modules" and "harvests SSH keys to perform lateral movement." <!--adsense--> The feature-packed

What is post-quantum cryptography? A new type of computer is being developed that can break many of our existing cryptographic algorithms. As a result, we need to develop new algorithms that are secure against those computers and that will run on our existing computers. This is called "post-quantum cryptography".

Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter Notebook. Prior to version 1.17.1, if notebook server is started with a value of `root_dir` that contains the starting user's home directory, then the underlying REST API can be used to leak the access token assigned at start time by guessing/brute forcing the PID of the jupyter server. While this requires an authenticated user session, this URL can be used from a cross-site scripting payload or from a hooked or otherwise compromised browser to leak this access token to a malicious third party. This token can be used along with the REST API to interact with Jupyter services/notebooks such as modifying or overwriting critical files, such as .bashrc or .ssh/authorized_keys, allowing a malicious user to read potentially sensitive data and possibly gain control of the impacted system. This issue is patched in version 1.17.1.

Jupyter Notebook is a web-based notebook environment for interactive computing. Prior to version 6.4.12, authenticated requests to the notebook server with `ContentsManager.allow_hidden = False` only prevented listing the contents of hidden directories, not accessing individual hidden files or files in hidden directories (i.e. hidden files were 'hidden' but not 'inaccessible'). This could lead to notebook configurations allowing authenticated access to files that may reasonably be expected to be disallowed. Because fully authenticated requests are required, this is of relatively low impact. But if a server's root directory contains sensitive files whose only protection from the server is being hidden (e.g. `~/.ssh` while serving $HOME), then any authenticated requests could access files if their names are guessable. Such contexts also necessarily have full access to the server and therefore execution permissions, which also generally grants access to all the same files. So this does no...

A memory leak (out-of-memory) in gif2rgb in util/gif2rgb.c in giflib 5.1.4 allows remote attackers trigger an out of memory exception or denial of service via a gif format file.

Symbiote, discovered in November, parasitically infects running processes so it can steal credentials, gain rootlkit functionality and install a backdoor for remote access.

Rakuten Casa version AP_F_V1_4_1 or AP_F_V2_0_0 uses a hard-coded credential which may allow a remote unauthenticated attacker to log in with the root privilege and perform an arbitrary operation.

A vulnerability was found in SICUNET Access Controller 0.32-05z. It has been declared as problematic. This vulnerability affects unknown code of the component Password Storage. The manipulation leads to weak encryption. Attacking locally is a requirement.
