TITLE:
Affix "affix_sock_register()" Privilege Escalation Vulnerability

SECUNIA ADVISORY ID:
SA15086

VERIFY ADVISORY:
http://secunia.com/advisories/15086/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
Affix 2.x
http://secunia.com/product/4965/

DESCRIPTION:
Kevin Finisterre has reported a vulnerability in Affix, which may be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to a boundary error in the
"affix_sock_register()" function in "hci.c". This may be exploited to
execute arbitrary code inside the kernel by supplying a negative
protocol value when creating a socket for the "PF_AFFIX"
communication domain.

SOLUTION:
Grant only trusted users access to affected systems.

The vulnerability will reportedly be fixed in an upcoming version.

PROVIDED AND/OR DISCOVERED BY:
