TITLE:
DAHDI "ZT_SPANCONFIG" IOCTL Privilege Escalation Vulnerability

SECUNIA ADVISORY ID:
SA32960

VERIFY ADVISORY:
http://secunia.com/advisories/32960/

CRITICAL:
Not critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
DAHDI 2.x
http://secunia.com/advisories/product/20645/

DESCRIPTION:
A vulnerability has been reported in DAHDI, which potentially can be
exploited by malicious, local users to gain escalated privileges.

The vulnerability is caused due to the "tor2_spanconfig()" function
in tor2.c not properly sanitising the "sync" field of the
"ZT_SPANCONFIG" IOCTL. This can potentially be exploited to gain
escalated privileges by sending a specially crafted "ZT_SPANCONFIG"
IOCTL to the vulnerable driver.

Successful exploitation requires that the driver for the "Tormenta 2
Quad-T1 PCI" card is used.

SOLUTION:
Fixed in version 2.1-rc5.
