This week on the Lock and Code podcast, we speak with Suzanne Bernstein about DNA privacy and protecting data from hackers.
### Summary The [`tj-actions/verify-changed-files`](https://github.com/tj-actions/verify-changed-files) action allows for command injection in changed filenames, allowing an attacker to execute arbitrary code and potentially leak secrets. ### Details The [`verify-changed-files`](https://github.com/tj-actions/verify-changed-files) workflow returns the list of files changed within a workflow execution. This could potentially allow filenames that contain special characters such as `;` and \` (backtick) which can be used by an attacker to take over the [GitHub Runner](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners) if the output value is used in a raw fashion (thus being directly replaced before execution) inside a `run` block. By running custom commands an attacker may be able to steal **secrets** such as `GITHUB_TOKEN` if triggered on other events than `pull_request`. For example on `push`. #### Proof of Concept 1. Submit a pull request to ...
### Summary The `tj-actions/changed-files` workflow allows for command injection in changed filenames, allowing an attacker to execute arbitrary code and potentially leak secrets. ### Details The [`changed-files`](https://github.com/tj-actions/changed-files) action returns a list of files changed in a commit or pull request which provides an `escape_json` input [enabled by default](https://github.com/tj-actions/changed-files/blob/94549999469dbfa032becf298d95c87a14c34394/action.yml#L136), only escapes `"` for JSON values. This could potentially allow filenames that contain special characters such as `;` and \` (backtick) which can be used by an attacker to take over the [GitHub Runner](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners) if the output value is used in a raw fashion (thus being directly replaced before execution) inside a `run` block.

### Impact An issue was discovered in the FamStructWrapper::deserialize implementation provided by the crate for vmm_sys_util::fam::FamStructWrapper, which can lead to out of bounds memory accesses. The deserialization does not check that the length stored in the header matches the flexible array length. Mismatch in the lengths might allow out of bounds memory access through Rust-safe methods. Impacted versions: >= 0.5.0 ### Patches The issue was corrected in version 0.12.0 by inserting a check that verifies the lengths of compared flexible arrays are equal for any deserialized header and aborting deserialization otherwise. Moreover, the API was changed so that header length can only be modified through Rust-unsafe code. This ensures that users cannot trigger out-of-bounds memory access from Rust-safe code.
### Impact Users with access to backend forms that include a [ColorPicker FormWidget](https://wintercms.com/docs/v1.2/docs/backend/forms#color-picker) can provide a value that would then be included without further processing in the compilation of custom stylesheets via LESS. This had the potential to lead to a Local File Inclusion vulnerability. By default, only the Brand Settings (backend.manage_branding) and Mail Brand Settings (system.manage_mail_templates) forms both include the colorpicker formwidget and pass the provided value to be compiled in LESS, however it is also common for themes to include it on their Theme Customization (cms.manage_theme_options) form and it is technically possible for the values on that form to also be used in LESS compilation: https://wintercms.com/docs/v1.2/docs/themes/development#asset-compiler-variables. ### Patches This issue has been patched in v1.2.4. ### Workarounds Apply https://github.com/wintercms/winter/commit/5bc9257fe2bc47d8b786a1b1bf9...
Ubuntu Security Notice 6563-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Marcus Brinkmann discovered that Thunderbird did not properly parse a PGP/MIME payload that contains digitally signed text. An attacker could potentially exploit this issue to spoof an email message.
FTPDMIN version 0.96 suffers from a denial of service vulnerability.
Ultra Mini HTTPd version 1.21 suffers from a denial of service vulnerability.
If you're at high risk of being targeted by mercenary spyware, or just don't mind losing iOS features for extra security, the company's restricted mode is surprisingly usable.
