Redhat has announced security fixes for xpdf (with Important severity).
Unfortunatelly, patches are not publicly available at the moment and CVE
entry is locked.
We have to wait for few days, so this is here as reminder, to not forget

Thanks Martin. You are right. We already have this fix.
I have just seen security advisory from Redhat (from yesterday) and CVE
entry is not public, so I thought that it is a new xpdf bug. This email
was intended to keep this issue on my radar.
Nevertheless, it is rather weird, because Redhat guys are one of the
most active in keeping xpdf code alive and provide many security bug
fixes. This patch is already incorporated in xpdf-3.02 tar ball!
