______________________________________________________________________________
An update that solves two vulnerabilities and has 10 fixes is now available.
Description:
This update for xen fixes the following issues:
Security issues fixed:
o Fixed multiple access violations introduced by XENMEM_exchange hypercall
which could allow a single PV guest to leak arbitrary amounts of memory,
leading to a denial of service (bsc#1126192).
o Fixed an issue which could allow a malicious unprivileged guest userspace
process to escalate its privilege to that of other userspace processes in
the same guest and potentially thereby to that of the guest operating
system (bsc#1126201).
o Fixed an issue which could allow an untrusted PV domain with access to a
physical device to DMA into its own pagetables leading to privilege
escalation (bsc#1126195).
o Fixed an issue which could allow a malicious or buggy x86 PV guest kernels
can mount a Denial of Service attack affecting the whole system (bsc#
1126196).
o CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp
(bsc#1123157).
o Fixed an issue which could allow malicious PV guests may cause a host crash
or gain access to data pertaining to other guests.Additionally, vulnerable
configurations are likely to be unstable even in the absence of an attack
(bsc#1126198).
o Fixed an issue which could allow malicious 64bit PV guests to cause a host
crash (bsc#1127400).
o Fixed an issue which could allow malicious or buggy guests with passed
through PCI devices to be able to escalate their privileges, crash the
host, or access data belonging to other guests. Additionally memory leaks
were also possible (bsc#1126140).
o Fixed a race condition issue which could allow malicious PV guests to
escalate their privilege to that of the hypervisor (bsc#1126141).
o CVE-2019-9824: Fixed an information leak in SLiRP networking implementation
which could allow a user/process to read uninitialised stack memory
contents (bsc#1129623).
Other issues fixed:
o Fixed an issue where VMs crashing when migrating between dom0 hosts (bsc#
1031382).
o Upstream bug fixes (bsc#1027519)

Description:
This update for xen fixes the following issues:
Security issues fixed:
o CVE-2018-18849: Fixed an out of bounds memory access issue that was found
in the LSI53C895A SCSI Host Bus Adapter emulation while writing a message
in lsi_do_msgin. It could occur during migration if the 'msg_len' field has
an invalid value. A user/process could use this flaw to crash the Qemu
process resulting in DoS (bsc#1114423).
o CVE-2018-19967: Fixed HLE constructs that allowed guests to lock up the
host, resulting in a Denial of Service (DoS). (XSA-282) (bsc#1114988)
o CVE-2018-19665: Fixed an integer overflow in Bluetooth routines allows
memory corruption (bsc#1117756).
o CVE-2018-18438: Fixed an integer overflow in ccid_card_vscard_read function
which allows memory corruption (bsc#1112188).
o CVE-2018-17962: Fixed a Buffer Overflow in pcnet_receive in hw/net/pcnet.c
because an incorrect integer data type is used (bsc#1111011).
o Fixed an issue which could allow a malicious unprivileged guest userspace
process to escalate its privilege to that of other userspace processes in
the same guest and potentially thereby to that of the guest operating
system (bsc#1126201).
o CVE-2018-19961 CVE-2018-19962: Fixed insufficient TLB flushing / improper
large page mappings with AMD IOMMUs (XSA-275)(bsc#1115040).
o CVE-2018-17963: Fixed qemu_deliver_packet_iov in net/net.c that accepts
packet sizes greater than INT_MAX, which allows attackers to cause a denial
of service or possibly have unspecified other impact. (bsc#1111014)
o Fixed an issue which could allow an untrusted PV domain with access to a
physical device to DMA into its own pagetables leading to privilege
escalation (bsc#1126195).
o Fixed an issue which could allow a malicious or buggy x86 PV guest kernels
can mount a Denial of Service attack affecting the whole system (bsc#
1126196)
o CVE-2018-17958: Fixed a Buffer Overflow in rtl8139_do_receive in hw/net/
rtl8139.c because an incorrect integer data type is used (bsc#1111007).

overflow issue (bsc#1110924).
o CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp
(bsc#1123157).
o CVE-2018-19966: Fixed issue introduced by XSA-240 that could have caused
conflicts with shadow paging (XSA-280)(bsc#1115047).

through PCI devices to be able to escalate their privileges, crash the
host, or access data belonging to other guests. Additionally memory leaks
were also possible (bsc#1126140).
o Fixed a race condition issue which could allow malicious PV guests to
escalate their privilege to that of the hypervisor (bsc#1126141).

An update that solves 14 vulnerabilities and has four fixes is now available.
Description:
This update for xen fixes the following issues:
Security issues fixed:
o CVE-2018-19965: Fixed an issue related to the INVPCID instruction in case
non-canonical addresses are accessed, which may allow a guest to cause Xen
to crash, resulting in a Denial of Service (DoS) affecting the entire host.
(XSA-279) (bsc#1115045)
o CVE-2018-18849: Fixed an out of bounds memory access issue was found in the
LSI53C895A SCSI Host Bus Adapter emulation while writing a message in
lsi_do_msgin (bsc#1114423).
o CVE-2018-19665: Fixed an integer overflow resulting in memory corruption in
various Bluetooth functions, allowing this to crash qemu process resulting
in Denial of Service (DoS). (bsc#1117756).
o CVE-2018-18438: Fixed an integer overflow in ccid_card_vscard_read function
which could allow memory corruption (bsc#1112188).
o CVE-2018-17962: Fixed an integer overflow leading to a buffer overflow in
the pcnet component (bsc#1111011)
o CVE-2018-17963: Fixed an integer overflow in relation to large packet
sizes, leading to a denial of service (DoS). (bsc#1111014)
o Fixed an issue which could allow an untrusted PV domain with access to a
physical device to DMA into its own pagetables leading to privilege
escalation (bsc#1126195).
o Fixed an issue which could allow a malicious or buggy x86 PV guest kernels
can mount a Denial of Service attack affecting the whole system (bsc#
1126196).
o CVE-2018-17958: Fixed an integer overflow which could lead to buffer
overflow (bsc#1111007).
o CVE-2018-10839: Fixed an integer overflow leading to a buffer overflow in
the ne2000 component (bsc#1110924).
o CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp
(bsc#1123157).
o CVE-2018-19966: Fixed issue introduced by XSA-240 that could have caused
conflicts with shadow paging (XSA-280)(bsc#1115047).
o CVE-2018-19967: Fixed HLE constructs that allowed guests to lock up the
host, resulting in a Denial of Service (DoS). (XSA-282) (bsc#1114988).
o Fixed multiple access violations introduced by XENMEM_exchange hypercall
which could allow a single PV guest to leak arbitrary amounts of memory,
leading to a denial of service (bsc#1126192).
o Fixed an issue which could allow malicious or buggy guests with passed
through PCI devices to be able to escalate their privileges, crash the
host, or access data belonging to other guests. Additionally memory leaks
were also possible (bsc#1126140).
o Fixed a race condition issue which could allow malicious PV guests to
escalate their privilege to that of the hypervisor (bsc#1126141).
o CVE-2019-9824: Fixed an information leak in SLiRP networking implementation
which could allow a user/process to read uninitialised stack memory
contents (bsc#1129623).
