Description Jan Lieskovsky 2011-10-12 13:46:07 UTC
An insecure temporary file use flaw was found in the way atop, an advanced interactive monitor to view the load on system and process level, has kept its temporary runtime data in temporary files. A local attacker could use this flaw to conduct symlink attacks (make atop to remove file named 'atop.acct' in the linked-to directory).

I think these are addressed in 1.26.  I'll get that out immediately and have a deeper look.
