Announcement ID: SUSE-SU-2017:1135-1 Rating: important References: #1013285 #1014109 #1014111 #1014702 #1015048 #1015169 #1016779 #1021129 #1023004 #1023053 #1023907 #1024972 Cross-References: CVE-2016-10155 CVE-2016-9776 CVE-2016-9907 CVE-2016-9911 CVE-2016-9921 CVE-2016-9922 CVE-2017-2615 CVE-2017-2620 CVE-2017-5856 CVE-2017-5898 Affected Products: SUSE Linux Enterprise Server 11-SP4 ______________________________________________________________________________
An update that solves 10 vulnerabilities and has two fixes is now available.
Description:
This update for kvm 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#1024972) - 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) - CVE-2016-9776: The ColdFire Fast Ethernet Controller emulator support was vulnerable to an infinite loop issue while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could have used this issue to crash the Qemu process on the host leading to DoS (bsc#1013285) - CVE-2016-9911: The USB EHCI Emulation support was vulnerable to a memory leakage issue while processing packet data in 'ehci_init_transfer'. A guest user/process could have used this issue to leak host memory, resulting in DoS for the host (bsc#1014111) - CVE-2016-9907: The USB redirector usb-guest support was vulnerable to a memory leakage flaw when destroying the USB redirector in 'usbredir_handle_destroy'. A guest user/process could have used this issue to leak host memory, resulting in DoS for a host (bsc#1014109) - 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#1014702) - CVE-2016-9922: 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#1014702) - CVE-2017-5898: The CCID Card device emulator support was vulnerable to an integer overflow allowing a privileged user inside the guest to crash the Qemu process resulting in DoS (bnc#1023907) - CVE-2016-10155: The virtual hardware watchdog 'wdt_i6300esb' was vulnerable to a memory leakage issue allowing a privileged user to cause a DoS and/or potentially crash the Qemu process on the host (bsc#1021129) - CVE-2017-5856: The MegaRAID SAS 8708EM2 Host Bus Adapter emulation support was vulnerable to a memory leakage issue allowing a privileged user to leak host memory resulting in DoS (bsc#1023053)
These non-security issues were fixed:
- Fixed various inaccuracies in cirrus vga device emulation - Fixed virtio interface failure (bsc#1015048) - Fixed graphical update errors introduced by previous security fix (bsc#1016779)
