Description
The vulnerability allows a remote attacker to gain elevated privileges on the target system.
The weakness exists in the implementation of the posix_memalign in memalign functions due to integer overflow when causing these functions to return a pointer to a heap area that is too small. A remote attacker can trigger memory corruption and gain root privileges.
