Vulnerability details

The vulnerability allows a local user to gain access to sensitive information or perform a denial of service (DoS) attack.

The bnep_sock_ioctl function in net/bluetooth/bnep/sock.c in the Linux kernel before 2.6.39 does not ensure that a certain device field ends with a '�' character, which allows local users to obtain potentially sensitive information from kernel stack memory, or cause a denial of service (BUG and system crash), via a BNEPCONNADD command.

Linux kernel
Ubuntu
linux (Ubuntu package)
linux-lts-backport-maverick (Ubuntu package)
