Since Linux-HA Heartbeat has insecure default permissions set on shared memory, local attackers may be able to cause a denial of service.
|
||
|
||
Exploitation would most likely result in a system crash, loss of data, and resource exhaustion, leading to a denial of service if critical files are accessed improperly or overwritten in the attack. Other attacks may be possible as well.

*
|
||
* ------ Shared Memory Segments --------
|
||
* key shmid owner perms bytes nattch status
|

*
|
||
* ------ Semaphore Arrays --------
|
||
* ....
|
||
* Get shmid of heartbeat(look perms == 666, this is wrong!!!:))
|
||
*
|
||
* [security@mail1 tmp]$ ./itts_sharedex2 1638402 "Intruders Tiger Team Security.."
