Fedora 8: 2008-8980 Moderate: Kernel Splice Function Threat

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. . --------------------------------------------------------------------------------Fedora Update Notification FEDORA-2008-8980 2008-10-23 16:03:13 --------------------------------------------------------------------------------Name : kernel Product : Fedora 8 Version : 2.6.26.6 Release : 49.fc8 URL : https://www.kernel.org/ Summary : The Linux kernel Description : The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system. The kernel handles the basic functions of the operating system: memory allocation, process allocation, device input and output, etc. --------------------------------------------------------------------------------Update Information: Update kernel from version 2.6.26.5 to 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.
