Linux kernel 32bit emulation code allows elevated privileges
| linux-32bit-emulation-gain-privileges (18686) |  High Risk |
Description:
Linux kernel version 2.4.x running on AMD64 / Intel EM64T systems could alllow a local attacker to gain elevated privileges on the system, caused by a vulnerability in the 32bit system call emulation code.
