security advisoryRed Hat Enterprise LinuximportantCritical Kernel Exploit in Red Hat 7.1 RHSA-2016:1657-01 Advisory
An update for kernel is now available for Red Hat Enterprise Linux 7.1 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score,. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ==================================================================== Red Hat Security Advisory Synopsis: Important: kernel security update Advisory ID: RHSA-2016:1657-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2016:1657.html Issue date: 2016-08-23 CVE Names: CVE-2016-4470 CVE-2016-4565 CVE-2016-5696 ==================================================================== 1. Summary: An update for kernel is now available for Red Hat Enterprise Linux 7.1 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux ComputeNode EUS (v. 7.1) - noarch, x86_64 Red Hat Enterprise Linux ComputeNode Optional EUS (v. 7.1) - x86_64 Red Hat Enterprise Linux Server EUS (v. 7.1) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 7.1) - ppc64, ppc64le, s390x, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix(es): * A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important) * A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead toinsufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system. (CVE-2016-4565, Important) * A flaw was found in the implementation of the Linux kernel's handling of networking challenge ack where an attacker is able to determine the shared counter which could be used to determine sequence numbers for TCP stream injection. (CVE-2016-5696, Important) Red Hat would like to thank Jann Horn for reporting CVE-2016-4565 and Yue Cao (Cyber Security Group of the CS department of University of California in Riverside) for reporting CVE-2016-5696. The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.). 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 The system must be rebooted for this update to take effect. 5. Bugs fixed (https://bugzilla.redhat.com/): 1310570 - CVE-2016-4565 kernel: infiniband: Unprivileged process can overwrite kernel memory using rdma_ucm.ko 1341716 - CVE-2016-4470 kernel: Uninitialized variable in request_key handling causes kernel crash in error handling path 1354708 - CVE-2016-5696 kernel: challenge ACK counter information disclosure. 6.

Description: The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. Following feature was added to kernel-xen: - A improved XEN blkfront module was added, which allows more I/O bandwidth. (FATE#320200) It is called xen-blkfront in PV, and xen-vbd-upstream in HVM mode. The following security bugs were fixed: - CVE-2013-7446: Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel allowed local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls (bnc#955654). - CVE-2015-7515: An out of bounds memory access in the aiptek USB driver could be used by physical local attackers to crash the kernel (bnc#956708). - CVE-2015-7550: The keyctl_read_key function in security/keys/keyctl.c in the Linux kernel did not properly use a semaphore, which allowed local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact via a crafted application that leverages a race condition between keyctl_revoke and keyctl_read calls (bnc#958951). - CVE-2015-8539: The KEYS subsystem in the Linux kernel allowed local users to gain privileges or cause a denial of service (BUG) via crafted keyctl commands that negatively instantiate a key, related to security/keys/encrypted-keys/encrypted.c, security/keys/trusted.c, and security/keys/user_defined.c (bnc#958463). - CVE-2015-8543: The networking implementation in the Linux kernel did not validate protocol identifiers for certain protocol families, which allowed local users to cause a denial of service (NULL function pointer dereference and system crash) or possibly gain privileges by leveraging CLONE_NEWUSER support toexecute a crafted SOCK_RAW application (bnc#958886). - CVE-2015-8550: Compiler optimizations in the XEN PV backend drivers could have lead to double fetch vulnerabilities, causing denial of service or arbitrary code execution (depending on the configuration) (bsc#957988). - CVE-2015-8551, CVE-2015-8552: xen/pciback: For XEN_PCI_OP_disable_msi[|x] only disable if device has MSI(X) enabled (bsc#957990). - CVE-2015-8569: The (1) pptp_bind and (2) pptp_connect functions in drivers/net/ppp/pptp.c in the Linux kernel did not verify an address length, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application (bnc#959190). - CVE-2015-8575: The sco_sock_bind function in net/bluetooth/sco.c in the Linux kernel did not verify an address length, which allowed local users to obtain sensitive information from kernel memory and bypass the KASLR protection mechanism via a crafted application (bnc#959190 bnc#959399). - CVE-2015-8767: net/sctp/sm_sideeffect.c in the Linux kernel did not properly manage the relationship between a lock and a socket, which allowed local users to cause a denial of service (deadlock) via a crafted sctp_accept call (bnc#961509). - CVE-2015-8785: The fuse_fill_write_pages function in fs/fuse/file.c in the Linux kernel allowed local users to cause a denial of service (infinite loop) via a writev system call that triggers a zero length for the first segment of an iov (bnc#963765). - CVE-2015-8812: A use-after-free flaw was found in the CXGB3 kernel driver when the network was considered to be congested. This could be used by local attackers to cause machine crashes or potentially code execution (bsc#966437). - CVE-2016-0723: Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel allowed local users to obtain sensitive information from kernelmemory or cause a denial of service (use-after-free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call (bnc#961500). - CVE-2016-2069: Race conditions in TLB syncing was fixed which could leak to information leaks (bnc#963767). - CVE-2016-2384: Removed a double free in the ALSA usb-audio driver in the umidi object which could lead to crashes (bsc#966693). - CVE-2016-2543: Added a missing NULL check at remove_events ioctl in ALSA that could lead to crashes. (bsc#967972). - CVE-2016-2544, CVE-2016-2545, CVE-2016-2546, CVE-2016-2547, CVE-2016-2548, CVE-2016-2549: Various race conditions in ALSAs timer handling were fixed.
