An update that solves six vulnerabilities and has three security fixes can now be installed.

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). (bsc#1114423)

Other bugs fixed:

• Fixed an issue related to a domU hang on SLE12-SP3 HV (bsc#1108940)
• Fixed an issue with xpti=no-dom0 not working as expected (bsc#1105528)
• Fixed an issue with live migrations, which used to fail when spectre is enabled on xen boot cmdline (bsc#1116380)
• Upstream bug fixes (bsc#1027519)
