The Linux kernel on SUSE Linux 10.0 has been updated to fix following security problems: - CVE-2006-0454: An extra dst release when ip_options_echo failed was fixed. This problem could be triggered by remote attackers and can potentially crash the machine. This is possible even with SuSEfirewall2 enabled. This affects only SUSE Linux 10.0, all other SUSE distributions are not affected. - CVE-2005-3356: A double decrement in mq_open system call could lead to local users crashing the machine. - CVE-2005-3358: A 0 argument passed to the set_mempolicy() system call could lead to a local user crashing the machine. - CVE-2005-4605: Kernel memory could be leaked to user space through a problem with seek() in /proc files . - CVE-2005-3623: Remote users could set ACLs even on read-only exported NFS Filesystems and so circumvent access control. - CVE-2005-3808: A 32 bit integer overflow on 64bit mmap calls could be used by local users to hang the machine. - CVE-2005-4635: Add sanity checks for headers and payload of netlink messages, which could be used by local attackers to crash the machine. Also various non-security bugs were fixed: - Fix up patch for cpufreq drivers that do not initialize current freq. - Handle BIOS cpufreq changes gracefully. - Updates to inotify handling. - Various XEN Updates. - Catches processor declarations with same ACPI id (P4HT) - PowerPC: g5 thermal overtemp bug on fluid cooled systems. - Fixed buffered ACPI events on a lot ASUS and some other machines. - Fix fs/exec.c:788 (de_thread()) BUG_ON (OSDL 5170). last seen 2019-10-28 modified 2006-02-10 plugin id 20879 published 2006-02-10 reporter This script is Copyright (C) 2006-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/20879 title SUSE-SA:2006:006: kernel
