Description Aron Griffis (RETIRED) gentoo-dev 2004-06-23 07:39:27 UTC
Bug 22483 describes a security issue with tempfile creation in znew and gzexe.  That problem was theoretically fixed and a glsa sent out.

However the patch doesn't check the exit status of the tempfile command.  If tempfile should fail, then it's possible for a rogue command to be executed a few lines later in the script.

I've fixed the patch and bumped the stable rev to 1.3.3-r3 to carry out the change.  At this point we just need a GLSA.  Somebody from security mind handling that?

GLSA drafted

GLSA updated with unaffected version -r4 and better description. Security please review.

Note: Changelog is not updated with new -r4

That was a ChangeLog error: it said -r3 instead of -r4.  I just fixed it now.
