Kevin Finisterre reports that affix, a package used to manage bluetooth sessions under Linux, uses the popen call in an unsafe fashion. A remote attacker can exploit this vulnerability to execute arbitrary commands on a vulnerable system.
The old stable distribution (woody) does not contain the affix package.
For the stable distribution (sarge) this problem has been fixed in version 2.1.1-3.
For the unstable distribution (sid) this problem has been fixed in version 2.1.2-3.
We recommend that you upgrade your affix package.
