New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated kernel packages that fix a number of security issues as well as other bugs are now available for Red Hat Enterprise Linux 2.1 (32 bit architectures)

This security advisory has been rated as having important security impact by the Red Hat Security Response Team.

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues described below :

- a flaw in network IGMP processing that a allowed a remote user on the local network to cause a denial of service (disabling of multicast reports) if the system is running multicast applications (CVE-2002-2185, moderate)

- a race condition that allowed local users to read the environment variables of another process (CVE-2004-1058, low)

- a flaw in the open_exec function of execve that allowed a local user to read setuid ELF binaries that should otherwise be protected by standard permissions.
(CVE-2004-1073, moderate). Red Hat originally reported this flaw as being fixed by RHSA-2004:504, but a patch for this issue was missing from that update.

- a flaw in the coda module that allowed a local user to cause a denial of service (crash) or possibly gain privileges (CVE-2005-0124, moderate)

- a potential leak of kernel data from ext2 file system handling (CVE-2005-0400, low)

- flaws in ISO-9660 file system handling that allowed the mounting of an invalid image on a CD-ROM to cause a denial of service (crash) or potentially execute arbitrary code (CVE-2005-0815, moderate)

- a flaw in gzip/zlib handling internal to the kernel that may allow a local user to cause a denial of service (crash) (CVE-2005-2458, low)

- a flaw in procfs handling during unloading of modules that allowed a local user to cause a denial of service or potentially gain privileges (CVE-2005-2709, moderate)

- a flaw in IPv6 network UDP port hash table lookups that allowed a local user to cause a denial of service (hang) (CVE-2005-2973, important)

- a network buffer info leak using the orinoco driver that allowed a remote user to possibly view uninitialized data (CVE-2005-3180, important)

- a flaw in IPv4 network TCP and UDP netfilter handling that allowed a local user to cause a denial of service (crash) (CVE-2005-3275, important)

- a flaw in the IPv6 flowlabel code that allowed a local user to cause a denial of service (crash) (CVE-2005-3806, important)

The following bugs were also addressed :

- Handle set_brk() errors in binfmt_elf/aout

- Correct error handling in shmem_ioctl

- Correct scsi error return

- Fix netdump time keeping bug

- Fix netdump link-down freeze

- Fix FAT fs deadlock

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.

Solution

Update the affected packages.
