CVE-2019-8381
https://notcve.org/view.php?id=CVE-2019-8381
An issue was discovered in Tcpreplay 4.3.1. An invalid memory access occurs in do_checksum in checksum.c. It can be triggered by sending a crafted pcap file to the tcpreplay-edit binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact. Se ha descubierto un problema en Tcpreplay 4.3.1. • https://github.com/appneta/tcpreplay/issues/538 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/4V3SADKXUSHWTVAPU3WLXBDEQUHRA6ZO https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EB3ASS7URTIA3IFSBL2DIWJAFKTBJCAW https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/MLPY6W7Z7G6PF2JN4LXXHCACYLD4RBG6 https://research.loginsoft.com/bugs/invalid-memory-access-vulnerability-in-function-do_checksum-tcpreplay-4-3-1 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVE-2019-7221 – Kernel: KVM: nVMX: use-after-free of the hrtimer for emulation of the preemption timer
https://notcve.org/view.php?id=CVE-2019-7221
The KVM implementation in the Linux kernel through 4.20.5 has a Use-after-Free. La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene un uso de memoria previamente liberada. A use-after-free vulnerability was found in the way the Linux kernel's KVM hypervisor emulates a preemption timer for L2 guests when nested (=1) virtualization is enabled. This high resolution timer(hrtimer) runs when a L2 guest is active. After VM exit, the sync_vmcs12() timer object is stopped. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00042.html http://packetstormsecurity.com/files/151713/KVM-VMX-Preemption-Timer-Use-After-Free.html http://www.openwall.com/lists/oss-security/2019/02/18/2 https://access.redhat.com/errata/RHBA-2019:0959 https://access.redhat.com/errata/RHSA-2019:0818 https://access.redhat.com/errata/RHSA-2019:0833 https://access.redhat.com/errata/RHSA-2019:3967 https://access.redhat.com/errata/RHSA-2019:4058 https://bugs.chromiu • CWE-416: Use After Free •
CVE-2019-7222 – Kernel: KVM: leak of uninitialized stack contents to guest
https://notcve.org/view.php?id=CVE-2019-7222
The KVM implementation in the Linux kernel through 4.20.5 has an Information Leak. La implementación KVM en el kernel de Linux, hasta la versión 4.20.5, tiene una fuga de información. An information leakage issue was found in the way Linux kernel's KVM hypervisor handled page fault exceptions while emulating instructions like VMXON, VMCLEAR, VMPTRLD, and VMWRITE with memory address as an operand. It occurs if the operand is a mmio address, as the returned exception object holds uninitialized stack memory contents. A guest user/process could use this flaw to leak host's stack memory contents to a guest. • http://lists.opensuse.org/opensuse-security-announce/2019-02/msg00042.html http://packetstormsecurity.com/files/151712/KVM-kvm_inject_page_fault-Uninitialized-Memory-Leak.html http://www.openwall.com/lists/oss-security/2019/02/18/2 http://www.securityfocus.com/bid/106963 https://access.redhat.com/errata/RHSA-2019:2029 https://access.redhat.com/errata/RHSA-2019:2043 https://access.redhat.com/errata/RHSA-2019:3309 https://access.redhat.com/errata/RHSA-2019:3517 https://bugs.chromiu • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
