CVE-2019-10167

libvirt: arbitrary command execution via virConnectGetDomainCapabilities API

The virConnectGetDomainCapabilities() libvirt API, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, accepts an "emulatorbin" argument to specify the program providing emulation for a domain. Since v1.2.19, libvirt will execute that program to probe the domain's capabilities. Read-only clients could specify an arbitrary path for this argument, causing libvirtd to execute a crafted executable with its own privileges.

CVE-2019-10166

libvirt: virDomainManagedSaveDefineXML API exposed to readonly clients

It was discovered that libvirtd, versions 4.x.x before 4.10.1 and 5.x.x before 5.4.1, would permit readonly clients to use the virDomainManagedSaveDefineXML() API, which would permit them to modify managed save state files. If a managed save had already been created by a privileged user, a local attacker could modify this file such that libvirtd would execute an arbitrary program when the domain was resumed.

CVE-2019-10161

libvirt: arbitrary file read/exec via virDomainSaveImageGetXMLDesc API

It was discovered that libvirtd before versions 4.10.1 and 5.4.1 would permit read-only clients to use the virDomainSaveImageGetXMLDesc() API, specifying an arbitrary path which would be accessed with the permissions of the libvirtd process. An attacker with access to the libvirtd socket could use this to probe the existence of arbitrary files, cause denial of service or cause libvirtd to execute arbitrary programs.

slf4j: Deserialisation vulnerability in EventData constructor can allow for arbitrary code execution

org.slf4j.ext.EventData in the slf4j-ext module in QOS.CH SLF4J before 1.8.0-beta2 allows remote attackers to bypass intended access restrictions via crafted data. EventData in the slf4j-ext module in QOS.CH SLF4J, has been fixed in SLF4J versions 1.7.26 later and in the 2.0.x series.

kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service

A flaw was found affecting the Linux kernel before version 4.17. By mmap()ing a FUSE-backed file onto a process's memory containing command line arguments (or environment strings), an attacker can cause utilities from psutils or procps (such as ps, w) or any other program which makes a read() call to the /proc/<pid>/cmdline (or /proc/<pid>/environ) files to block indefinitely (denial of service) or for some controlled time (as a synchronization primitive for other attacks).
