8cc is vulnerable to an Out‑of‑Bounds Read due to improper handling of #line directives and GNU linemarkers. The compiler accepts attacker-controlled filename and line number metadata and later uses it without validation when accessing source line arrays. By supplying invalid or oversized line numbers, an attacker can trigger out-of-bounds memory access and a crash. Maintainer of this project was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Version corresponding to the commit b480958 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

**Name of the Vulnerable Software and Affected Versions** GNU nano versions prior to 9.0 **Description** GNU nano creates the user's `~/.local` directory with overly permissive permissions when it does not already exist. During the first use of features requiring Cross-Desktop Group (XDG) data storage, the software requests directory mode 0777. In environments with a relaxed or zero umask (such as container environments, CI/CD runners, embedded systems, or shells configured with umask 000), this makes the directory world-writable. A local attacker can exploit a race window between the creation of `~/.local` and the subsequent creation of more restrictive subdirectories to write controlled files into the victim's XDG directory hierarchy. **Recommendations** Update to version 9.0.

**Name of the Vulnerable Software and Affected Versions** phpPgAdmin version 4.1.1 **Description** The issue is related to a cross-site scripting (XSS) vulnerability. This vulnerability allows remote attackers to inject arbitrary web script or HTML via the `server` parameter in the sqledit.php file. **Recommendations** For phpPgAdmin version 4.1.1, consider restricting access to the sqledit.php file until a patch is available. As a temporary workaround, avoid using the `server` parameter in the sqledit.php file to minimize the risk of exploitation.
