Description Guilherme de Almeida Suckevicz 2021-11-17 16:50:37 UTC 
libarchive before 3.5.2, when opening a file descriptor to set file flags on Linux, would follow symbolic links. In case an archive contains a directory entry followed by a symlink entry with the same path, libarchive would modify file flags of the symlink target.
