Linux kernel IP packet denial of service
| linux-ip-packet-dos (17800) |  Medium Risk |
Description:
Linux kernel is vulnerable to a denial of service attack, caused by an integer underflow in the iptables firewall logging rules. If firewalling is enabled, a remote attacker could send a specially-crafted IP packet to cause the system to crash.
Consequences:
Denial of Service
Remedy:
Upgrade to the latest version of Linux kernel (2.6.8 or later), available from the Linux Kernel Web site. See References.
For Debian GNU/Linux:
Refer to DSA-1017-1 or DSA-1018-2 for patch, upgrade, or suggested workaround information. See References.
For SuSE Linux:
Upgrade to the latest kernel package, as listed below. Refer to SuSE Security Announcement SUSE-SA:2004:037 for more information. See References.
SuSE Linux 9.1: 2.6.5-7.111 or later
For SUSE Linux:
Upgrade to the latest kernel, as listed below. Refer to SUSE Security Announcement SUSE-SA:2005:018 for more information. See References.
