Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The uu_mv crate (uutils mv) before 0.7.0 is affected. When moving a directory across filesystems, it follows symlinks inside the tree and copies their targets rather than preserving the links, so a small tree can expand into a very large copy, sensitive paths can be duplicated, and symlink loops can cause deep recursion. The source gives few details on who can supply the tree. Upgrade uu_mv to 0.7.0 or later.
