What is CVE-2008-5744?
The DAHDI (formerly Zaptel) driver contains an array index error in the tor2.c implementation. This vulnerability allows local users, specifically those in the dialout group, to manipulate kernel memory by writing to the /dev/zap/ctl interface. The flaw is tied to an improper implementation in a previously released patch for CVE-2008-5396, where an incorrect variable was utilized in a range check. Consequently, this oversight enables local users to overwrite critical integer values in kernel memory, posing a significant threat to system stability and security.
