### Summary:

- Commits: 4
- Commit Authors: 2
- Issues Resolved: 0
- Security Advisories Resolved: 4
- GHSA-85x7-54wr-vh42: Asterisk xml.c uses unsafe XML_PARSE_NOENT leading to potential XXE Injection
- GHSA-rvch-3jmx-3jf3: ast_coredumper running as root sources ast_debug_tools.conf from /etc/asterisk; potentially leading to privilege escalation
- GHSA-v6hp-wh3r-cwxh: The Asterisk embedded web server's /httpstatus page echos user supplied values(cookie and query string) without sanitization
- GHSA-xpc6-x892-v83c: ast_coredumper runs as root, and writes gdb init file to world writeable folder; leading to potential privilege escalation

### User Notes:

- #### ast_coredumper: check ast_debug_tools.conf permissions

  ast_debug_tools.conf must be owned by root and not be writable by other users or groups to be used by ast_coredumper or by ast_logescalator or ast_loggrabber when run as root.

### Upgrade Notes:

- #### http.c: Change httpstatus to default disabled and sanitize output.

  To prevent possible security issues, the `/httpstatus` page served by the internal web server is now disabled by default. To explicitly enable it, set `enable_status=yes` in http.conf.

### Commit List:

- xml.c: Replace XML_PARSE_NOENT with XML_PARSE_NONET for xmlReadFile.
- ast_coredumper: check ast_debug_tools.conf permissions
- http.c: Change httpstatus to default disabled and sanitize output.
- ast_coredumper: create gdbinit file with restrictive permissions

### Commit Details:

#### xml.c: Replace XML_PARSE_NOENT with XML_PARSE_NONET for xmlReadFile.

Author: George Joseph Date: 2026-01-15

The xmlReadFile XML_PARSE_NOENT flag, which allows parsing of external entities, could allow a potential XXE injection attack. Replacing it with XML_PARSE_NONET, which prevents network access, is safer.

Resolves: #GHSA-85x7-54wr-vh42

#### ast_coredumper: check ast_debug_tools.conf permissions

Author: Mike Bradeen Date: 2026-01-15

Prevent ast_coredumper from using ast_debug_tools.conf files that are not owned by root or are writable by other users or groups.

Prevent ast_logescalator and ast_loggrabber from doing the same if they are run as root.

Resolves: #GHSA-rvch-3jmx-3jf3

UserNote: ast_debug_tools.conf must be owned by root and not be writable by other users or groups to be used by ast_coredumper or by ast_logescalator or ast_loggrabber when run as root.

#### http.c: Change httpstatus to default disabled and sanitize output.

Author: George Joseph Date: 2026-01-15

To address potential security issues, the httpstatus page is now disabled by default and the echoed query string and cookie output is html-escaped.

Resolves: #GHSA-v6hp-wh3r-cwxh

UpgradeNote: To prevent possible security issues, the `/httpstatus` page served by the internal web server is now disabled by default. To explicitly enable it, set `enable_status=yes` in http.conf.

#### ast_coredumper: create gdbinit file with restrictive permissions

Author: Mike Bradeen Date: 2026-01-15

Modify gdbinit to use the install command with explicit permissions (-m 600) when creating the .ast_coredumper.gdbinit file. This ensures the file is created with restricted permissions (readable/writable only by the owner) to avoid potential privilege escalation.

Resolves: #GHSA-xpc6-x892-v83c
