CVE-2008-5396: n/a vulnerability

CVE-2008-5396: Array index error in the (1) torisa.c and (2) dahdi/tor2.c drivers in Zaptel (aka DAHDI) 1.4.11 and earlier...

Array index error in the (1) torisa.c and (2) dahdi/tor2.c drivers in Zaptel (aka DAHDI) 1.4.11 and earlier allows local users in the dialout group to overwrite an integer value in kernel memory by writing to /dev/zap/ctl, related to missing validation of the sync field associated with the ZT_SPANCONFIG ioctl.

Security readout for executives and security teams

This is a legacy Linux telephony driver issue in Zaptel/DAHDI 1.4.11 and earlier. A local user in the dialout group could misuse a control interface to overwrite an integer in kernel memory. The main business concern is older PBX or telephony hosts with local user access or broad dialout permissions. Exposure is most likely on old Asterisk/PBX or telephony systems running Zaptel/DAHDI 1.4.11 or earlier with torisa or tor2 drivers and users in the dialout group. Treat this as a targeted legacy-system risk. It is not described as remote or actively exploited, but kernel memory corruption on PBX infrastructure can affect availability and host integrity if local access controls are weak. Mitigation focus: Inventory systems for Zaptel or DAHDI 1.4.11 and earlier.; Restrict dialout group membership to trusted administrative or telephony service accounts.; Review permissions on /dev/zap/ctl and related telephony device nodes..
