Replacing it with\n  XML_PARSE_NONET, which prevents network access, is safer.\n\n  Resolves: #GHSA-85x7-54wr-vh42\n\n#### ast_coredumper: check ast_debug_tools.conf permissions\n  Author: Mike Bradeen\n  Date:   2026-01-15\n\n  Prevent ast_coredumper from using ast_debug_tools.conf files that are\n  not owned by root or are writable by other users or groups.\n\n  Prevent ast_logescalator and ast_loggrabber from doing the same if\n  they are run as root.\n\n  Resolves: #GHSA-rvch-3jmx-3jf3\n\n  UserNote: ast_debug_tools.conf must be owned by root and not be\n  writable by other users or groups to be used by ast_coredumper or\n  by ast_logescalator or ast_loggrabber when run as root.\n\n#### http.c: Change httpstatus to default disabled and sanitize output.\n  Author: George Joseph\n  Date:   2026-01-15\n\n  To address potential security issues, the httpstatus page is now disabled\n  by default and the echoed query string and cookie output is html-escaped.\n\n  Resolves: #GHSA-v6hp-wh3r-cwxh\n\n  UpgradeNote: To prevent possible security issues, the `/httpstatus` page\n  served by the internal web server is now disabled by default.  To explicitly\n  enable it, set `enable_status=yes` in http.conf.\n\n#### ast_coredumper: create gdbinit file with restrictive permissions\n  Author: Mike Bradeen\n  Date:   2026-01-15\n\n  Modify gdbinit to use the install command with explicit permissions (-m 600)\n  when creating the .ast_coredumper.gdbinit file. This ensures the file is\n  created with restricted permissions (readable/writable only by the owner)\n  to avoid potential privilege escalation.\n\n  Resolves: #GHSA-xpc6-x892-v83c\n\n_______________________________________________\nSent through the Full Disclosure mailing list\nhttps://nmap.org/mailman/listinfo/fulldisclosure\nWeb Archives \u0026 RSS: https://seclists.org/fulldisclosure/"
