Severity: normal

[ Reason ]

This fixes CVE-2025-63261: AWStats 8.0 is vulnerable to Command Injection via the open function.

[ Impact ]

In some situations, mostly concerning web hosting panels, a malicious user with write privileges to the local filesystem may run arbitrary commands, possibly as a different awstats system user.

[ Tests ]

I reproduced the issue and ensured it didn't happen with the fix.

I deployed the (very small) fix on 3 web servers that I administrate, and that run awstats hourly, to ensure no regression occurred.

The same fix was published to bullseye-lts and buster-elts last month, no issues reported.

I ran common Debian tests through debusine:
https://debusine.debian.net/debian/developers/work-request/555861/

[ Risks ]

The fix is trivial and is a textbook example of insecure old-style Perl open, causing confusion between a filename with a trailing '|' and a request to pipe input from arbitrary commands:
https://perldoc.perl.org/functions/open#Specifying-mode-and-filename-as-a-single-argument
https://perldoc.perl.org/functions/open#Whitespace-and-special-characters-in-the-filename-argument

[ Checklist ]

  [X] *all* changes are documented in the d/changelog
  [X] I reviewed all changes and I approve them
  [X] attach debdiff against the package in (old)stable
  [X] the issue is verified as fixed in unstable

[ Changes ]

Add CVE-2025-63261.patch with a one-liner fix.

[ Other info ]

Binary debdiff show that NEWS.Debian.gz is dropped, due to NEWS pruning in slightly newer debhelper (#1021607 - last entry was from 2006).
