Otklonjena je nova sigurnosna ranjivost vezana uz APT pozadinski proces (Aptdaemon), koji običnim korisnicima omogućuje upravljanje i ažuriranje raznovrsnih programskih paketa. Uočena ranjivost javlja se zbog neispravne provjere pojedinih argumenata prilikom korištenja D-Bus sučelja. Napadač može iskoristiti takvu ranjivost kako bi zaobišao ugrađene sigurnosne mehanizme i došao do povjerljivih informacija. S obzirom na to da je objavljena nadogradnja ranjivog programskog paketa koja ispravlja opisanu ranjivost, svim se korisnicima savjetuje njena primjena.

===========================================================

A security issue affects the following Ubuntu releases:

Ubuntu 10.10

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

The problem can be corrected by upgrading your system to the
following package versions:

Ubuntu 10.10:
  python-aptdaemon                0.31+bzr506-0ubuntu6.1

In general, a standard system update will make all the necessary changes.

arguments when using its D-Bus interface. A local attacker could use this
flaw to bypass security restrictions and view sensitive information by
reading arbitrary files.
