- CVEs with nessus.description==This update for xen fixes several issues. These security issues were
fixed :
- CVE-2017-2620: In CIRRUS_BLTMODE_MEMSYSSRC mode the
bitblit copy routine cirrus_bitblt_cputovideo failed to
check the memory region, allowing for an out-of-bounds
write that allows for privilege escalation
(bsc#1024834).
- CVE-2017-2615: An error in the bitblt copy operation
could have allowed a malicious guest administrator to
cause an out of bounds memory access, possibly leading
to information disclosure or privilege escalation
(bsc#1023004).
- A malicious guest could have, by frequently rebooting
over extended periods of time, run the host system out
of memory, resulting in a Denial of Service (DoS)
(bsc#1022871)
- CVE-2016-9921: The Cirrus CLGD 54xx VGA Emulator support
was vulnerable to a divide by zero issue while copying
VGA data. A privileged user inside guest could have used
this flaw to crash the process instance on the host,
resulting in DoS (bsc#1015169
The update package also includes non-security fixes. See advisory for
