An update that solves 7 vulnerabilities and has one errata is now available.
Description:
This update for qemu fixes the following issues:
Security issues fixed:
- CVE-2018-10839: Fixed NE2000 NIC emulation support that is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash the Qemu process resulting in DoS (bsc#1110910). - CVE-2018-15746: Fixed qemu-seccomp.c that might allow local OS guest users to cause a denial of service (guest crash) by leveraging mishandling of the seccomp policy for threads other than the main thread (bsc#1106222). - CVE-2018-17958: Fixed a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used (bsc#1111006). - CVE-2018-17962: Fixed a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used (bsc#1111010). - CVE-2018-17963: Fixed qemu_deliver_packet_iov in net/net.c that accepts packet sizes greater than INT_MAX, which allows attackers to cause a denial of service or possibly have unspecified other impact. (bsc#1111013) - CVE-2018-18849: Fixed an out of bounds memory access issue that was found in the LSI53C895A SCSI Host Bus Adapter emulation while writing a message in lsi_do_msgin. It could occur during migration if the 'msg_len' field has an invalid value. A user/process could use this flaw to crash the Qemu process resulting in DoS (bsc#1114422). - CVE-2018-16847: Fixed an out of bounds r/w buffer access in cmb operations (bsc#1114529).
Non-security issue fixed:
- Fixed a condition when retry logic does not have been executed in case of data transmit failure or connection hungup (bsc#1108474).
