is now available.
Description:
This update for xen fixes the following issues:
Security issues fixed:
- 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)
- 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).
- 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).
- CVE-2018-18438: Fixed an integer overflow in ccid_card_vscard_read
function which could allow memory corruption (bsc#1112188).
- CVE-2018-17962: Fixed an integer overflow leading to a buffer overflow
in the pcnet component (bsc#1111011)
- CVE-2018-17963: Fixed an integer overflow in relation to large packet
sizes, leading to a denial of service (DoS). (bsc#1111014)
- 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).
- 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).
- CVE-2018-17958: Fixed an integer overflow which could lead to buffer
overflow (bsc#1111007).
- CVE-2018-10839: Fixed an integer overflow leading to a buffer overflow
in the ne2000 component (bsc#1110924).
- CVE-2019-6778: Fixed a heap buffer overflow in tcp_emu() found in slirp
(bsc#1123157).
- CVE-2018-19966: Fixed issue introduced by XSA-240 that could have caused
conflicts with shadow paging (XSA-280)(bsc#1115047).
- 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).
- 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).
- 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).
- Fixed a race condition issue which could allow malicious PV guests to
escalate their privilege to that
of the hypervisor (bsc#1126141).
- 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).
