  - CVE-2017-14316: Missing bound check in function
    `alloc_heap_pages` for an internal array allowed
    attackers using crafted hypercalls to execute arbitrary
    code within Xen (XSA-231, bsc#1056278)

  - CVE-2017-14318: The function __gnttab_cache_flush missed
    a check for grant tables, allowing a malicious guest to
    crash the host or for x86 PV guests to potentially
    escalate privileges (XSA-232, bsc#1056280)

  - CVE-2017-14317: A race in cxenstored may have cause a
    double-free allowind for DoS of the xenstored daemon
    (XSA-233, bsc#1056281).

  - CVE-2017-14319: An error while handling grant mappings
    allowed malicious or buggy x86 PV guest to escalate its
    privileges or crash the hypervisor (XSA-234,
    bsc#1056282).

The update package also includes non-security fixes. See advisory for
details.

Jan Beulich discovered multiple places where reference counting on
grant table operations was incorrect, resulting in potential privilege
escalation

CVE-2017-12135

Jan Beulich found multiple problems in the handling of transitive
grants which could result in denial of service and potentially
privilege escalation.

CVE-2017-12137

Andrew Cooper discovered that incorrect validation of grants may
result in privilege escalation.

CVE-2017-12855

Jan Beulich discovered that incorrect grant status handling, thus
incorrectly informing the guest that the grant is no longer in use.

CVE-2017-14316

Matthew Daley discovered that the NUMA node parameter wasn't verified
which which may result in privilege escalation.

CVE-2017-14317

Eric Chanudet discovered that a race conditions in cxenstored might
result in information leaks or privilege escalation.

CVE-2017-14318

Matthew Daley discovered that incorrect validation of grants may
result in a denial of service.

CVE-2017-14319

Andrew Cooper discovered that insufficient grant unmapping checks may
result in denial of service and privilege escalation.

For Debian 7 'Wheezy', these problems have been fixed in version
4.1.6.lts1-9.

These security issues were fixed :

  - CVE-2017-14316: Missing bound check in function

    attackers using crafted hypercalls to execute arbitrary
    code within Xen (XSA-231, bsc#1056278)

  - CVE-2017-14318: The function __gnttab_cache_flush missed
    a check for grant tables, allowing a malicious guest to
    crash the host or for x86 PV guests to potentially
    escalate privileges (XSA-232, bsc#1056280)

  - CVE-2017-14317: A race in cxenstored may have cause a
    double-free allowind for DoS of the xenstored daemon
    (XSA-233, bsc#1056281).

  - CVE-2017-14319: An error while handling grant mappings
    allowed malicious or buggy x86 PV guest to escalate its
    privileges or crash the hypervisor (XSA-234,
    bsc#1056282).

These non-security issues were fixed :

  - bsc#1055695: Fixed restoring updates for HVM guests for
    ballooned domUs

"This update for xen fixes several issues.

These security issues were fixed :

  - CVE-2017-14316: Missing bound check in function
    `alloc_heap_pages` for an internal array allowed
    attackers using crafted hypercalls to execute arbitrary
    code within Xen (XSA-231, bsc#1056278)

  - CVE-2017-14318: The function __gnttab_cache_flush missed
    a check for grant tables, allowing a malicious guest to
    crash the host or for x86 PV guests to potentially
    escalate privileges (XSA-232, bsc#1056280)

  - CVE-2017-14317: A race in cxenstored may have cause a
    double-free allowind for DoS of the xenstored daemon
    (XSA-233, bsc#1056281).

  - CVE-2017-14319: An error while handling grant mappings
    allowed malicious or buggy x86 PV guest to escalate its
    privileges or crash the hypervisor (XSA-234,
    bsc#1056282).

These non-security issues were fixed :

  - bsc#1057358: Fixed boot into SUSE Linux Enterprise 12.3
    with secure boot

  - bsc#1055695: Fixed restoring updates for HVM guests for
    ballooned domUs

This update was imported from the SUSE:SLE-12-SP3:Update update
project."
