Hi everyone,
I'm glad to announce the new release of GNU screen.

Screen is a full-screen window manager that multiplexes a physical terminal
between several processes, typically interactive shells.

5.0.1 is a security fix release. It includes only a few code fixes, types
and security issues. It doesn't include any new features.

   - CVE-2025-46805: do NOT send signals with root privileges
   - CVE-2025-46804: avoid file existence test information leaks
   - CVE-2025-46803: apply safe PTY default mode of 0620
   - CVE-2025-46802: prevent temporary 0666 mode on PTYs in attacher
   - CVE-2025-23395: reintroduce lf_secreopen() for logfile
   - buffer overflow due bad strncpy()
   - uninitialized variables warnings
   - typos
   - combining char handling that could lead to a segfault


Release (official tarball) will be available soon for download:
https://ftp.gnu.org/gnu/screen/
Please report any bugs or regressions.
Thanks to everyone who contributed to this release.

Cheers,
Alex
