Description of problem:
How reproducible:
Steps to Reproduce:
Actual results:

[me@rhel6 ~]$ mktemp -t XXXXXX.pdf
/tmp/UQ75h2.pdf

Nice, OK!

[me@rhel5 ~]$ mktemp -t XXXXXX.pdf
/tmp/XXXXXX.pdf
[me@rhel5 ~]$ mktemp -t XXXXXX.pdf
mktemp: cannot create temp file /tmp/XXXXXX.pdf: File exists

Not so nice.

Expected results:
It would be nice if RHEL5 and RHEL6 would have same functionality.
Could this be a security issue if scripts expect RHEL6 functionality?

Version-Release number of selected component (if applicable):
mktemp-1.5-24.el5

Comment 1 Than Ngo 2014-10-23 13:44:40 UTC

mktemp is part coreutils since rhel6 and it's not the same what we have in rhel5.
If you take a look at the man pages, the correct syntax for mktemp is:

mktemp -r pp.XXXXXXX

In rhel6 mktemp also supports the syntax XXXXXX.pp. It's also not a bug but rather a feature. I don't think it's a security issue, the user should make sure that he uses the correct syntax.

Since rhel-5.10 new feature is not accepted anymore, so i closed it as NOTABUG
