Oracle Linux 6 : Unbreakable Enterprise kernel (ELSA-2017-3516)

high Nessus Plugin ID 97118

Language:

Synopsis

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

Description

The remote Oracle Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2017-3516 advisory.

 - The llc_cmsg_rcv function in net/llc/af_llc.c in the Linux kernel before 4.5.5 does not initialize a certain data structure, which allows attackers to obtain sensitive information from kernel stack memory by reading a message. (CVE-2016-4485)

 - The hash_accept function in crypto/algif_hash.c in the Linux kernel before 4.3.6 allows local users to cause a denial of service (OOPS) by attempting to trigger use of in-kernel hash algorithms for a socket that has received zero bytes of data. (CVE-2016-8646)

 - The proc_connectinfo function in drivers/usb/core/devio.c in the Linux kernel through 4.6 does not initialize a certain data structure, which allows local users to obtain sensitive information from kernel stack memory via a crafted USBDEVFS_CONNECTINFO ioctl call. (CVE-2016-4482)

 - Use-after-free vulnerability in net/unix/af_unix.c in the Linux kernel before 4.3.3 allows local users to bypass intended AF_UNIX socket permissions or cause a denial of service (panic) via crafted epoll_ctl calls. (CVE-2013-7446)

 - Race condition in the handle_to_path function in fs/fhandle.c in the Linux kernel through 3.19.1 allows local users to bypass intended size restrictions and trigger read operations on additional memory locations by changing the handle_bytes value of a file handle during the execution of this function.
 (CVE-2015-1420)

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.
