The remote Fedora host is missing a security update.
Update to kernel 220.127.116.11-rc1: http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-18.104.22.168 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-22.214.171.124 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-126.96.36.199 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-188.8.131.52 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-184.108.40.206 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-220.127.116.11 http://www.kernel.org/pub/linux/kernel/v2.6/ChangeLog-18.104.22.168 CVE-2007-5501: The tcp_sacktag_write_queue function in net/ipv4/tcp_input.c in Linux kernel 2.6.24-rc2 and earlier allows remote attackers to cause a denial of service (crash) via crafted ACK responses that trigger a NULL pointer dereference. CVE-2007-5500: The wait_task_stopped function in the Linux kernel before 22.214.171.124 checks a TASK_TRACED bit instead of an exit_state value, which allows local users to cause a denial of service (machine crash) via unspecified vectors. Additional fixes: Major wireless updates. Fix oops in netfilter NAT module (#259501) libata: fix resume on some systems libata: fix pata_serverworks with some drive combinations Initial FireWire OHCI 1.0 Isochronous Receive support (#344851) Disable USB autosuspend by default. Fix oops in CIFS when mounting a filesystem a second time. Restore platform module autoloading, e.g. pcspkr. Fix failure to boot on 486DX4 (and possibily other CPUs.) 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.
