Description

Update kernel from version 2.6.26.5 to 2.6.26.6: http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-2.6.26.6 CVE-2008-3831 An IOCTL in the i915 driver was not properly restricted to users with the proper capabilities to use it. CVE-2008-4410 The vmi_write_ldt_entry function in arch/x86/kernel/vmi_32.c in the Virtual Machine Interface (VMI) in the Linux kernel 2.6.26.5 invokes write_idt_entry where write_ldt_entry was intended, which allows local users to cause a denial of service (persistent application failure) via crafted function calls, related to the Java Runtime Environment (JRE) experiencing improper LDT selector state, a different vulnerability than CVE-2008-3247. CVE-2008-3525 The sbni_ioctl function in drivers/net/wan/sbni.c in the wan subsystem in the Linux kernel 2.6.26.3 does not check for the CAP_NET_ADMIN capability before processing a (1) SIOCDEVRESINSTATS, (2) SIOCDEVSHWSTATE, (3) SIOCDEVENSLAVE, or (4) SIOCDEVEMANSIPATE ioctl request, which allows local users to bypass intended capability restrictions. CVE-2008-4554 The do_splice_from function in fs/splice.c in the Linux kernel before 2.6.27 does not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file. CVE-2008-4576 sctp in Linux kernel before 2.6.25.18 allows remote attackers to cause a denial of service (OOPS) via an INIT-ACK that states the peer does not support AUTH, which causes the sctp_process_init function to clean up active transports and triggers the OOPS when the T1-Init timer expires.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
