- - quotes from CVE: |
| 19 |
|
| 20 |
"The route cache implementation in Linux 2.4, and the Netfilter IP |
| 21 |
conntrack module, allows remote attackers to cause a denial of service |
| 22 |
(CPU consumption) via packets with forged source addresses that cause a |
| 23 |
large number of hash table collisions." |
| 24 |
|
| 25 |
"The ioperm system call in Linux kernel 2.4.20 and earlier does not |
| 26 |
properly restrict privileges, which allows local users to gain read or |
| 27 |
write access to certain I/O ports." |
| 28 |
|
| 29 |
"A race condition in the way env_start and env_end pointers are |
| 30 |
initialized in the execve system call and used in fs/proc/base.c on |
| 31 |
Linux 2.4 allows local users to cause a denial of service (crash)." |
| 32 |
|
| 33 |
SOLUTION |
| 34 |
|
| 35 |
It is recommended that all Gentoo Linux users who are running |
| 36 |
sys-kernel/gentoo-sources upgrade to gentoo-sources-2.4.20-r6 as follows |
| 37 |
|
| 38 |
emerge sync |
| 39 |
emerge gentoo-sources |
| 40 |
emerge clean |
| 41 |
|
| 42 |
After that, compile, install and reboot your computer to complete |
| 43 |
the upgrade. |
