seunshare in policycoreutils 2.2.5 is owned by root with 4755 permissions, and executes programs in a way that changes the relationship between the setuid system call and the getresuid saved set-user-ID value, which makes it easier for local users to gain privileges by leveraging a program that mistakenly expected that it could permanently drop privileges.

The remote Redhat Enterprise Linux 5 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

  - policycoreutils: local privilege escalation via seunshare (CVE-2014-3215)

Note that Nessus has not tested for this issue but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by a vulnerability that has been acknowledged by the vendor but will not be patched.

libcap-ng was updated to fix one security issue. This security issue was fixed :

  - CVE-2014-3215: seunshare in policycoreutils (which uses     libcap-ng) is owned by root with 4755 permissions, and     executes programs in a way that changes the relationship     between the setuid system call and the getresuid saved     set-user-ID value, which made it easier for local users     to gain privileges by leveraging a program that     mistakenly expected that it could permanently drop     privileges (bsc#876832).

The remote OracleVM system is missing necessary patches to address critical security updates in kernel-uek.

The remote Oracle Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2015-3064 advisory.

  - The Linux kernel through 3.17.4 does not properly restrict dropping of supplemental group memberships in     certain namespace scenarios, which allows local users to bypass intended file permissions by leveraging a     POSIX ACL containing an entry for the group category that is more restrictive than the entry for the other     category, aka a negative groups issue, related to kernel/groups.c, kernel/uid16.c, and     kernel/user_namespace.c. (CVE-2014-8989)

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

A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system.

The remote Oracle Linux 5 / 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2015-3036 advisory.

  - Xen 3.3.x through 4.5.x and the Linux kernel through 3.19.1 do not properly restrict access to PCI command     registers, which might allow local guest OS users to cause a denial of service (non-maskable interrupt and     host crash) by disabling the (1) memory or (2) I/O decoding for a PCI Express device and then accessing     the device, which triggers an Unsupported Request (UR) response. (CVE-2015-2150)

  - The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before     3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-     dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute     arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an     AF_ALG(aead) socket.

Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

* A flaw was found in the way seunshare, a utility for running executables under a different security context, used the capng_lock functionality of the libcap-ng library. The subsequent invocation of suid root binaries that relied on the fact that the setuid() system call, among others, also sets the saved set-user-ID when dropping the binaries' process privileges, could allow a local, unprivileged user to potentially escalate their privileges on the system. Note: the fix for this issue is the kernel part of the overall fix, and introduces the PR_SET_NO_NEW_PRIVS functionality and the related SELinux exec transitions support. (CVE-2014-3215, Important)

* A use-after-free flaw was found in the way the Linux kernel's SCTP implementation handled authentication key reference counting during INIT collisions. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2015-1421, Important)

* It was found that the Linux kernel's KVM implementation did not ensure that the host CR4 control register value remained unchanged across VM entries on the same virtual CPU. A local, unprivileged user could use this flaw to cause a denial of service on the system.
(CVE-2014-3690, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's perf subsystem. A local, unprivileged user could use this flaw to crash the system.
(CVE-2014-7825, Moderate)

* An out-of-bounds memory access flaw was found in the syscall tracing functionality of the Linux kernel's ftrace subsystem. On a system with ftrace syscall tracing enabled, a local, unprivileged user could use this flaw to crash the system, or escalate their privileges.
(CVE-2014-7826, Moderate)

* It was found that the Linux kernel memory resource controller's (memcg) handling of OOM (out of memory) conditions could lead to deadlocks. An attacker able to continuously spawn new processes within a single memory-constrained cgroup during an OOM event could use this flaw to lock up the system. (CVE-2014-8171, Moderate)

* A race condition flaw was found in the way the Linux kernel keys management subsystem performed key garbage collection. A local attacker could attempt accessing a key while it was being garbage collected, which would cause the system to crash. (CVE-2014-9529, Moderate)

* A stack-based buffer overflow flaw was found in the TechnoTrend/Hauppauge DEC USB device driver. A local user with write access to the corresponding device could use this flaw to crash the kernel or, potentially, elevate their privileges on the system.
(CVE-2014-8884, Low)

* An information leak flaw was found in the way the Linux kernel's ISO9660 file system implementation accessed data on an ISO9660 image with RockRidge Extension Reference (ER) records. An attacker with physical access to the system could use this flaw to disclose up to 255 bytes of kernel memory. (CVE-2014-9584, Low)

Red Hat would like to thank Andy Lutomirski for reporting CVE-2014-3215 and CVE-2014-3690, Robert Swiecki for reporting CVE-2014-7825 and CVE-2014-7826, and Carl Henrik Lunde for reporting CVE-2014-9584. The CVE-2015-1421 issue was discovered by Sun Baoliang of Red Hat.

This update also fixes several bugs. Documentation for these changes is available from the Technical Notes document linked to in the References section.

All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

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

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

Updated libcap-ng packages fix security vulnerability :

capng_lock() in libcap-ng before 0.7.4 sets securebits in an attempt to prevent regaining capabilities using setuid-root programs. This allows a user to run setuid programs, such as seunshare from policycoreutils, as uid 0 but without capabilities, which is potentially dangerous (CVE-2014-3215).

The remote host is affected by the vulnerability described in GLSA-201412-44 (policycoreutils: Privilege escalation)

    The seunshare utility is owned by root with 4755 permissions which can       be exploited by a setuid system call.
  Impact :

    A local attacker may be able to gain escalated privileges.
  Workaround :

    There is no known workaround at this time.

Besides other enhancements, this version update contains :

  - fix for CVE-2014-3215 (bnc#876832)

  - use PR_SET_NO_NEW_PRIVS to prevent gain of new     privileges

  - added libcap-ng-CVE-2014-3215.patch
