Kitty version 0.76.0.8 suffers from a buffer overflow vulnerability.

Zyxel firewalls, AP controllers, and APs suffer from buffer overflow, format string, and command injection vulnerabilities.

The package github.com/argoproj/argo-events/sensors/artifacts before 1.7.1 are vulnerable to Directory Traversal in the (g *GitArtifactReader).Read() API in git.go. This could allow arbitrary file reads if the GitArtifactReader is provided a pathname containing a symbolic link or an implicit directory name such as ...

When running in debug mode and the `debug-embed` (off by default) feature is not enabled, the generated `get` method does not check that the input path is a child of the folder given. This allows attackers to read arbitrary files in the file system if they have control over the filename given. The following code will print the contents of your `/etc/passwd` if adjusted with a correct number of `../`s depending on where it is run from. ```rust #[derive(rust_embed::RustEmbed)] #[folder = "src/"] pub struct Asset; fn main() { let d = Asset::get("../../../etc/passwd").unwrap().data; println!("{}", String::from_utf8_lossy(&d)); } ``` The flaw was corrected by canonicalizing the input filename and ensuring that it starts with the canonicalized folder path.

Affects: Notebook and Lab between 6.4.0?(potentially earlier) and 6.4.11 (currently latest). Jupyter Server <=1.16.0. If I am correct about the responsible code it will affect Jupyter-Server 1.17.0 and 2.0.0a0 as well. Description: 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 an xss payload (as in CVE-2021-32798) 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.

### Impact _What kind of vulnerability is it? Who is impacted?_ 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 not generally result in any privilege esc...
