Description:
* SECURITY UPDATE: tarfile data/tar extraction filter bypassed by a hard
link whose target is a symlink
- debian/patches/CVE-2026-82049.patch: pass os.path.realpath() of the
hard-link source to os.link() in makelink_with_filter(), so the
extracted name is a hard link to the file the symlink resolves to
instead of a second name for the symlink inode itself. link(2) does
not follow symlinks, so without this a crafted archive could place a
copy of an already-extracted symlink one directory shallower, where
its relative payload re-bases outside the destination directory and
the chmod/utime that follow change the mode and mtime of the outside
file while exposing its contents inside the extracted tree (CWE-59).
Also carries upstream's test_sneaky_hardlink_relocation regression
test. This fix is effective only in combination with CVE-2026-11940,
which is already part of upstream 3.11.16 and blocks the variant that
never reaches os.link()
