Description Seiji Nishikawa 2014-05-29 10:50:39 UTC 
Description of problem:
 ksh not giving error on "cd" to directory without execute bit.
 It does not return an error if we "cd" to a directory without execute bit.

Version-Release number of selected component (if applicable):
 RHEL6.5 (2.6.32-431.5.1.el6.x86_64)
 ksh-20120801-10.el6_5.5.x86_64

How reproducible:
 100%

Steps to Reproduce:
1. Create a directory.
2. Run "chmod 660" to the directory.
3. When running "cd" to the directory, it does not return error "permission denied". "pwd" shows the path to the directory. But "ls" shows the contents of the previous path.

# ksh
$ pwd
/home/user001
$ ls
file01	file02
$ mkdir dir01
$ chmod 660 dir01
$ cd dir01
$ pwd
/home/user001/dir01
$ ls 
dir01  file01  file02
$ ll
total 4
drw-rw----. 2 user001 user001 4096 May 29 19:44 dir01
-rw-rw-r--. 1 user001 user001    0 May 29 19:43 file01
-rw-rw-r--. 1 user001 user001    0 May 29 19:43 file02

Actual results:
 It does not return error "permission denied". "pwd" shows the path to the directory. But "ls" shows the contents of the previous path.

Expected results:
 Error "permission Denied" should be returned against "cd" to a directory of which permission 660.
