Description:
This update for xen fixes the following issues:
Security vulnerabilities fixed:
- CVE-2018-19961, CVE-2018-19962: Fixed an issue related to insufficient
TLB flushing with AMD IOMMUs, which potentially allowed a guest to
escalate its privileges, may cause a Denial of Service (DoS) affecting
the entire host, or may be able to access data it is not supposed to
access. (XSA-275) (bsc#1115040)
- 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-2018-19966: Fixed an issue related to a previous fix for XSA-240,
which conflicted with shadow paging and allowed a guest to cause Xen to
crash, resulting in a Denial of Service (DoS). (XSA-280) (bsc#1115047)
- 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-2018-18849: Fixed an out of bounds memory access in the LSI53C895A
SCSI host bus adapter emulation, which allowed a user and/or process to
crash the qemu process resulting in a Denial of Service (DoS).
