Redhat Libvirt vulnerabilities

CVE-2011-2511 [MEDIUM] CWE-189 CVE-2011-2511: Integer overflow in libvirt before 0.9.3 allows remote authenticated users to cause a denial of serv Integer overflow in libvirt before 0.9.3 allows remote authenticated users to cause a denial of service (libvirtd crash) and possibly execute arbitrary code via a crafted VirDomainGetVcpus RPC call that triggers memory corruption.

CVE-2011-2178 [MEDIUM] CVE-2011-2178: The virSecurityManagerGetPrivateData function in security/security_manager.c in libvirt 0.8.8 throug The virSecurityManagerGetPrivateData function in security/security_manager.c in libvirt 0.8.8 through 0.9.1 uses the wrong argument for a sizeof call, which causes incorrect processing of "security manager private data" that "reopens disk probing" and might allow guest OS users to read arbitrary files on the host OS. NOTE: this vulnerability exists because of

CVE-2011-1486 [LOW] CWE-399 CVE-2011-1486: libvirtd in libvirt before 0.9.0 does not use thread-safe error reporting, which allows remote attac libvirtd in libvirt before 0.9.0 does not use thread-safe error reporting, which allows remote attackers to cause a denial of service (crash) by causing multiple threads to report errors at the same time.

CVE-2011-1146 [MEDIUM] CVE-2011-1146: libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only c libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only connection, which allows remote attackers to cause a denial of service (host OS crash) or possibly execute arbitrary code via a (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttac

CVE-2010-2238 [MEDIUM] CVE-2010-2238: Red Hat libvirt, possibly 0 Red Hat libvirt, possibly 0.7.2 through 0.8.2, recurses into disk-image backing stores without extracting the defined disk backing-store format, which might allow guest OS users to read arbitrary files on the host OS, and possibly have unspecified other impact, via unknown vectors.

CVE-2010-2239 [MEDIUM] CVE-2010-2239: Red Hat libvirt, possibly 0 Red Hat libvirt, possibly 0.6.0 through 0.8.2, creates new images without setting the user-defined backing-store format, which allows guest OS users to read arbitrary files on the host OS via unspecified vectors.

CVE-2010-2237 [MEDIUM] CVE-2010-2237: Red Hat libvirt, possibly 0 Red Hat libvirt, possibly 0.6.1 through 0.8.2, looks up disk backing stores without referring to the user-defined main disk format, which might allow guest OS users to read arbitrary files on the host OS, and possibly have unspecified other impact, via unknown vectors.

CVE-2010-2242 [LOW] CVE-2010-2242: Red Hat libvirt 0 Red Hat libvirt 0.2.0 through 0.8.2 creates iptables rules with improper mappings of privileged source ports, which allows guest OS users to bypass intended access restrictions by leveraging IP address and source-port values, as demonstrated by copying and deleting an NFS directory tree.

CVE-2009-0036 [MEDIUM] CVE-2009-0036: Buffer overflow in the proxyReadClientSocket function in proxy/libvirt_proxy Buffer overflow in the proxyReadClientSocket function in proxy/libvirt_proxy.c in libvirt_proxy 0.5.1 might allow local users to gain privileges by sending a portion of the header of a virProxyPacket packet, and then sending the remainder of the packet with crafted values in the header, related to use of uninitialized memory in a validation check.

CVE-2008-5086 [HIGH] CVE-2008-5086: Multiple methods in libvirt 0 Multiple methods in libvirt 0.3.2 through 0.5.1 do not check if a connection is read-only, which allows local users to bypass intended access restrictions and perform administrative actions.
