SUSE SLES12 Security Update : libvirt (SUSE-SU-2020:2233-1)

This update for libvirt fixes the following issues : CVE-2020-14339: Don't leak /dev/mapper/control into QEMU. Use ioctl's to obtain the dependency tree of disks and drop use of libdevmapper. - bsc1161883, bsc1174458 qemu: Setup emulator thread and cpuset.mems before exec - bsc1171946 libxl:...

The vulnerabilities of the functions rx_queue_add_kobject() and netdev_queue_add_kobject() (net/core/net-sysfs.c) in the Linux kernel allow attackers to compromise data integrity.

The vulnerability of the functions rxqueueaddkobject and netdevqueueaddkobject net/core/net-sysfs.c in the Linux kernel is related to errors in pointer counting in the networking subsystem. Exploiting this vulnerability could allow an attacker to compromise data integrity...

CVE-2019-20811

CVE-2019-20811 affects the Linux kernel prior to 5.0.6, where a reference count is mishandled in rx_queue_add_kobject() and netdev_queue_add_kobject() within net/core/net-sysfs.c (CID-a3e23f719f5c). The issue was fixed in kernel 5.0.6 (ChangeLog-5.0.6). Exploitation would require local access and...
