### Summary `gix-path` runs `git` to find the path of a configuration file associated with the `git` installation, but improperly resolves paths containing unusual or non-ASCII characters, in rare cases enabling a local attacker to inject configuration leading to code execution. ### Details In `gix_path::env`, the underlying implementation of the `installation_config` and `installation_config_prefix` functions calls `git config -l --show-origin` to find the path of a file to treat as belonging to the `git` installation. Affected versions of `gix-path` do not pass `-z`/`--null` to cause `git` to report literal paths (650a1b5cf25e086197cc55a68525a411e1c28031). Instead, to cover the occasional case that `git` outputs a quoted path, they attempt to parse the path by stripping the quotation marks: https://github.com/Byron/gitoxide/blob/1cfe577d461293879e91538dbc4bbfe01722e1e8/gix-path/src/env/git/mod.rs#L138-L142 The problem is that, when a path is quoted, it may change in substantial...
### Description The summary is that the proof of knowledge associated to a commitment is crucial to bind the commitment to the actual circuit variables that were supposed to be committed. However, the same σ is used for all proofs of knowledge for the commitments, which allows mixing between them, making it possible to fix the value of all but one commitment before choosing the circuit variable assignments. In more detail: To simplify notation, let us consider the case of two commitments, each to only a single variable. Let's say the basis elements for those commitments are `K_0` and `K_1`. Then the proving key will contain `K_0` and `K_1`, and also `σ*K_0` and `σ*K_1` for the proof of knowledge. The honest prover assigning a to the first circuit variable and b to the second will then produce commitments `D_0 = a*K_0` `D_1 = b*K_1` Out of the two D's, a challenge r for the commitment folding will be generated. The folded commitment will then be `D_folded = D_0 + r*D_1 = a*K_0 + r*b*K...
### Impact The vulnerability depends on user interaction by opening a malicious notebook with Markdown cells, or Markdown file using JupyterLab preview feature. A malicious user can access any data accessible from JupyterLite and perform arbitrary actions in JupyterLite environment. ### Patches JupyterLite 0.4.1 was patched. ### Workarounds There is no workaround for the underlying DOM Clobbering susceptibility. However, select plugins can be disabled on deployments which cannot update in a timely fashion to minimise the risk. These are: - `@jupyterlab/mathjax-extension:plugin` - users will loose ability to preview mathematical equations - `@jupyterlab/markdownviewer-extension:plugin` - users will loose ability to open Markdown previews - `@jupyterlab/mathjax2-extension:plugin` (if installed with optional `jupyterlab-mathjax2` package) - an older version of the mathjax plugin for JupyterLab 4.x To disable these extensions populate the `disabledExtensions` key in `jupyter-config...

### Impact XSLT transforms performed by various components are vulnerable to XML external entity injections. A processed XML file with a malicious DTD tag ( `<!DOCTYPE foo [<!ENTITY example SYSTEM "/etc/passwd"> ]>` could produce XML containing data from the host system. This impacts use cases where org.hl7.fhir.core is being used to within a host where external clients can submit XML. ### Patches This issue has been patched in release 6.3.23 ### Workarounds None. ### References [MITRE CWE](https://cwe.mitre.org/data/definitions/611.html) [OWASP XML External Entity Prevention Cheat Sheet](https://cheatsheetseries.owasp.org/cheatsheets/XML_External_Entity_Prevention_Cheat_Sheet.html#transformerfactory)
The vulnerabilities affect industrial control tech used across the healthcare and critical manufacturing sectors.
This report concerns the Groth16 prover when used with commitments (as in `frontend.Committer`). To simplify exposition of the issue, I will focus on the case of a single commitment, to only private witnesses. But the issue should be present whenever commitments are used that include private witnesses. > The commitment to private witnesses `w_i` is computed as ``` c = sum_i w_i * b_i ``` where `b_i` would be `ProvingKey.CommitmentKeys[0].Basis[i]` in the code. While this is a binding commitment, it is not hiding. In practice, an adversary will know the points `b_i`, as they are part of the proving key, and can verify correctness of a guess for the values of `w_i` by computing `c'` as the right hand side of the above formula, and checking whether `c'` is equal to `c`. I attach a proof of concept that demonstrates this. This breaks the perfect zero-knowledge property of Groth16, so the Groth16 scheme using commitments to private witnesses as implemented by gnark fails to be a zk-SNARK...
