Linux kernel FIFO denial of service
| linux-kernel-fifo-dos (42273) |  Low Risk |
Description:
Linux kernel is vulnerable to a denial of service, caused by an error in the FIFO file. By using asynchronous input or output, a local attacker could exploit this vulnerability to cause a kernel panic resulting in a denial of service.
Platforms Affected:
- Linux, Kernel 2.4.0
- Linux, Kernel 2.4.1
- Linux, Kernel 2.4.11
- Linux, Kernel 2.4.12
- Linux, Kernel 2.4.13
- Linux, Kernel 2.4.14
- Linux, Kernel 2.4.15
- Linux, Kernel 2.4.16
- Linux, Kernel 2.4.17
- Linux, Kernel 2.4.18
- Linux, Kernel 2.4.19
- Linux, Kernel 2.4.2
- Linux, Kernel 2.4.3
- Linux, Kernel 2.4.4
- Linux, Kernel 2.4.5
- Linux, Kernel 2.4.6
- Linux, Kernel 2.4.7
- Linux, Kernel 2.4.8
- Linux, Kernel 2.4.9
- RedHat, Enterprise Linux 3 ES
- RedHat, Enterprise Linux 3 AS
- RedHat, Enterprise Linux 3 Desktop
- RedHat, Enterprise Linux 3 WS
- VMware, ESX Server 3.0.1
- VMware, ESX Server 3.0.2
- VMware, ESX Server 3.5
Remedy:
Refer to Red Hat Bugzilla Bug 326251 for patch, upgrade or suggested workaround information. See References.
