2008-12-26 CVE-2008-5744 Numeric Errors vulnerability in Asterisk Zaptel 1.2/1.2.27/1.4
Array index error in the dahdi/tor2.c driver 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 an incorrect tor2 patch for CVE-2008-5396 that uses the wrong variable in a range check against the value of lc->sync.
