Oracle Linux 4 : kernel (ELSA-2006-0617 / ELSA-2006-0689)

High Nessus Plugin ID 67401

Synopsis

The remote Oracle Linux host is missing a security update.

Description

Updated kernel packages that fix security issues are now available.

This update 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 :


From Red Hat Security Advisory 2006-0617 :

* a flaw in the proc file system that allowed a local user to use a suid-wrapper for scripts to gain root privileges (CVE-2006-3626, Important)

* a flaw in the SCTP implementation that allowed a local user to cause a denial of service (panic) or to possibly gain root privileges (CVE-2006-3745, Important)

* a flaw in NFS exported ext2/ext3 partitions when handling invalid inodes that allowed a remote authenticated user to cause a denial of service (filesystem panic) (CVE-2006-3468, Important)

* a flaw in the restore_all code path of the 4/4GB split support of non-hugemem kernels that allowed a local user to cause a denial of service (panic) (CVE-2006-2932, Important)

* a flaw in IPv4 netfilter handling for the unlikely use of SNMP NAT processing that allowed a remote user to cause a denial of service (crash) or potential memory corruption (CVE-2006-2444, Moderate)

* a flaw in the DVD handling of the CDROM driver that could be used together with a custom built USB device to gain root privileges (CVE-2006-2935, Moderate)

* a flaw in the handling of O_DIRECT writes that allowed a local user to cause a denial of service (memory consumption) (CVE-2004-2660, Low)

* a flaw in the SCTP chunk length handling that allowed a remote user to cause a denial of service (crash) (CVE-2006-1858, Low)

* a flaw in the input handling of the ftdi_sio driver that allowed a local user to cause a denial of service (memory consumption) (CVE-2006-2936, Low)

In addition a bugfix was added to enable a clean reboot for the IBM Pizzaro machines.

Red Hat would like to thank Wei Wang of McAfee Avert Labs and Kirill Korotaev for reporting issues fixed in this erratum.


From Red Hat Security Advisory ELSA-2006-0689 :

* a flaw in the SCTP support that allowed a local user to cause a denial of service (crash) with a specific SO_LINGER value.
(CVE-2006-4535, Important)

* a flaw in the hugepage table support that allowed a local user to cause a denial of service (crash). (CVE-2005-4811, Important)

* a flaw in the mprotect system call that allowed setting write permission for a read-only attachment of shared memory.
(CVE-2006-2071, Moderate)

* a flaw in HID0[31] (en_attn) register handling on PowerPC 970 systems that allowed a local user to cause a denial of service.
(crash) (CVE-2006-4093, Moderate)

* a flaw in the perfmon support of Itanium systems that allowed a local user to cause a denial of service by consuming all file descriptors. (CVE-2006-3741, Moderate)

* a flaw in the ATM subsystem. On systems with installed ATM hardware and configured ATM support, a remote user could cause a denial of service (panic) by accessing socket buffers memory after freeing them.
(CVE-2006-4997, Moderate)

* a flaw in the DVB subsystem. On systems with installed DVB hardware and configured DVB support, a remote user could cause a denial of service (panic) by sending a ULE SNDU packet with length of 0.
(CVE-2006-4623, Low)

* an information leak in the network subsystem that possibly allowed a local user to read sensitive data from kernel memory. (CVE-2006-0039, Low)

In addition, two bugfixes for the IPW-2200 wireless driver were included. The first one ensures that wireless management applications correctly identify IPW-2200 controlled devices, while the second fix ensures that DHCP requests using the IPW-2200 operate correctly.

Red Hat would like to thank Olof Johansson, Stephane Eranian and Solar Designer for reporting issues fixed in this erratum.
