Synopsis

The remote MiracleLinux host is missing one or more security updates.

Description

The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2016-018:01 advisory.

Security issues fixed with this release:
CVE-2015-2925 The prepend_path function in fs/dcache.c in the Linux kernel before 4.2.4 does not properly handle rename actions inside a bind mount, which allows local users to bypass an intended container protection mechanism by renaming a directory, related to a double-chroot attack.
CVE-2015-5307 The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #AC (aka Alignment Check) exceptions, related to svm.c and vmx.c.
CVE-2015-7613 Race condition in the IPC object implementation in the Linux kernel through 4.2.3 allows local users to gain privileges by triggering an ipc_addid call that leads to uid and gid comparisons against uninitialized data, related to msg.c, shm.c, and util.c.
CVE-2015-7872 The key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 4.2.6 allows local users to cause a denial of service (OOPS) via crafted keyctl commands.
CVE-2015-8104 The KVM subsystem in the Linux kernel through 4.2.6, and Xen 4.3.x through 4.6.x, allows guest OS users to cause a denial of service (host OS panic or hang) by triggering many #DB (aka Debug) exceptions, related to svm.c.
Fixed bugs:
* Previously, Human Interface Device (HID) ran a report on an unaligned buffer, which could cause a page fault interrupt and an oops when the end of the report was read. This update fixes this bug by padding the end of the report with extra bytes, so the reading of the report never crosses a page boundary. As a result, a page fault and subsequent oops no longer occur.
* The NFS client was previously failing to detect a directory loop for some NFS server directory structures. This failure could cause NFS inodes to remain referenced after attempting to unmount the file system, leading to a kernel crash. Loop checks have been added to VFS, which effectively prevents this problem from occurring.
* Due to a race whereby the nfs_wb_pages_cancel() and nfs_commit_release_pages() calls both removed a request from the nfs_inode struct type, the kernel panicked with negative nfs_inode.npages count. The provided upstream patch performs the required serialization by holding the inode i_lock over the check of PagePrivate and locking the request, thus preventing the race and kernel panic from occurring.
* Due to incorrect URB_ISO_ASAP semantics, playing an audio file using a USB sound card could previously fail for some hardware configurations. This update fixes the bug, and playing audio from a USB sound card now works as expected.
* Inside hugetlb, region data structures were protected by a combination of a memory map semaphore and a single hugetlb instance mutex. However, a page-fault scalability improvement backported to the kernel on previous releases removed the single hugetlb instance mutex and introduced a new mutex table, making the locking combination insufficient, leading to possible race windows that could cause corruption and undefined behavior. This update fixes the problem by introducing a required spinlock to the region tracking functions for proper serialization. The problem only affects software using huge pages through hugetlb interface.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

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

Solution

Update the affected packages.
