Description

**Issue Overview:** Race condition in raw_sendmsg function allows denial-of-service or kernel addresses leak A flaw was found in the Linux kernel's implementation of raw_sendmsg allowing a local attacker to panic the kernel or possibly leak kernel addresses. A local attacker, with the privilege of creating raw sockets, can abuse a possible race condition when setting the socket option to allow the kernel to automatically create ip header values and thus potentially escalate their privileges. (CVE-2017-17712) Use-after-free vulnerability in DCCP socket A use-after-free vulnerability was found in DCCP socket code affecting the Linux kernel since 2.6.16. This vulnerability could allow an attacker to their escalate privileges. (CVE-2017-8824) Stack-based out-of-bounds read via vmcall instruction Linux kernel compiled with the KVM virtualization (CONFIG_KVM) support is vulnerable to an out-of-bounds read access issue. It could occur when emulating vmcall instructions invoked by a guest. A guest user/process could use this flaw to disclose kernel memory bytes. (CVE-2017-17741) Unchecked capabilities in net/netfilter/xt_osf.c allows for unprivileged modification to systemwide fingerprint list net/netfilter/xt_osf.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for add_callback and remove_callback operations, which allows local users to bypass intended access restrictions because the xt_osf_fingers data structure is shared across all net namespaces. (CVE-2017-17450) Missing capabilities check in net/netfilter/nfnetlink_cthelper.c allows for unprivileged access to systemwide nfnl_cthelper_list structure net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4 does not require the CAP_NET_ADMIN capability for new, get, and del operations, which allows local users to bypass intended access restrictions because the nfnl_cthelper_list data structure is shared across all net namespaces. (CVE-2017-17448) **Affected Packages:** kernel **Issue Correction:** Run _yum update kernel_ to update your system. You will need to reboot your system in order for the new kernel to be running. **New Packages:** i686:     kernel-tools-debuginfo-4.9.77-31.58.amzn1.i686     kernel-debuginfo-common-i686-4.9.77-31.58.amzn1.i686     kernel-devel-4.9.77-31.58.amzn1.i686     kernel-headers-4.9.77-31.58.amzn1.i686     kernel-4.9.77-31.58.amzn1.i686     kernel-debuginfo-4.9.77-31.58.amzn1.i686     kernel-tools-4.9.77-31.58.amzn1.i686     kernel-tools-devel-4.9.77-31.58.amzn1.i686     perf-debuginfo-4.9.77-31.58.amzn1.i686     perf-4.9.77-31.58.amzn1.i686 noarch:     kernel-doc-4.9.77-31.58.amzn1.noarch src:     kernel-4.9.77-31.58.amzn1.src x86_64:     perf-4.9.77-31.58.amzn1.x86_64     kernel-devel-4.9.77-31.58.amzn1.x86_64     kernel-4.9.77-31.58.amzn1.x86_64     kernel-tools-debuginfo-4.9.77-31.58.amzn1.x86_64     kernel-tools-devel-4.9.77-31.58.amzn1.x86_64     kernel-headers-4.9.77-31.58.amzn1.x86_64     kernel-tools-4.9.77-31.58.amzn1.x86_64     perf-debuginfo-4.9.77-31.58.amzn1.x86_64     kernel-debuginfo-common-x86_64-4.9.77-31.58.amzn1.x86_64     kernel-debuginfo-4.9.77-31.58.amzn1.x86_64
