Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-0290 advisory.

 - arch/x86/kvm/vmx.c in the KVM subsystem in the Linux kernel before 3.17.2 on Intel processors does not ensure that the value in the CR4 control register remains the same after a VM entry, which allows host OS users to kill arbitrary processes or cause a denial of service (system disruption) by leveraging /dev/kvm access, as demonstrated by PR_SET_TSC prctl calls within a modified copy of QEMU. (CVE-2014-3690)

 - The Linux kernel through 3.14.5 does not properly consider the presence of hugetlb entries, which allows local users to cause a denial of service (memory corruption or system crash) by accessing certain memory locations, as demonstrated by triggering a race condition via numa_maps read operations during hugepage migration, related to fs/proc/task_mmu.c and mm/mempolicy.c. (CVE-2014-3940)

 - kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the perf subsystem, which allows local users to cause a denial of service (out-of- bounds read and OOPS) or bypass the ASLR protection mechanism via a crafted application. (CVE-2014-7825)

 - kernel/trace/trace_syscalls.c in the Linux kernel through 3.17.2 does not properly handle private syscall numbers during use of the ftrace subsystem, which allows local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application. (CVE-2014-7826)

 - Race condition in the ext4_file_write_iter function in fs/ext4/file.c in the Linux kernel through 3.17 allows local users to cause a denial of service (file unavailability) via a combination of a write action and an F_SETFL fcntl operation for the O_DIRECT flag. (CVE-2014-8086)

 - net/netfilter/nf_conntrack_proto_generic.c in the Linux kernel before 3.18 generates incorrect conntrack entries during handling of certain iptables rule sets for the SCTP, DCCP, GRE, and UDP-Lite protocols, which allows remote attackers to bypass intended access restrictions via packets with disallowed port numbers. (CVE-2014-8160)

 - The filesystem implementation in the Linux kernel before 3.13 performs certain operations on lists of files with an inappropriate locking approach, which allows local users to cause a denial of service (soft lockup or system crash) via unspecified use of Asynchronous I/O (AIO) operations. (CVE-2014-8172)

 - The pmd_none_or_trans_huge_or_clear_bad function in include/asm-generic/pgtable.h in the Linux kernel before 3.13 on NUMA systems does not properly determine whether a Page Middle Directory (PMD) entry is a transparent huge-table entry, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted MADV_WILLNEED madvise system call that leverages the absence of a page-table lock. (CVE-2014-8173)

 - The ieee80211_fragment function in net/mac80211/tx.c in the Linux kernel before 3.13.5 does not properly maintain a certain tail pointer, which allows remote attackers to obtain sensitive cleartext information by reading packets. (CVE-2014-8709)

 - Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call.
 (CVE-2014-8884)

 - The XFS implementation in the Linux kernel before 3.15 improperly uses an old size value during remote attribute replacement, which allows local users to cause a denial of service (transaction overrun and data corruption) or possibly gain privileges by leveraging XFS filesystem access. (CVE-2015-0274)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
