that the uploaded binary packages really fix the problem this time.
Unfortunately the bugfix from DSA 102-1 wasn't propagated properly due
to a packaging bug. While the file parsetime.y was fixed, and
yy.tab.c should be generated from it, yy.tab.c from the original
source was still used. This has been fixed now.
The original advisory said:
zen-parse found a bug in the current implementation of at which leads
into a heap corruption vulnerability which in turn could potentially
lead into an exploit of the daemon user.
This has been fixed in at 3.1.8-10.2 for the stable Debian release and
3.1.8-11 for the unstable and testing release. We
recommend that you upgrade your at packages immediately since an
exploit has already been published.");
