A code execution vulnerability exists in the DL_Dxf::handleLWPolylineData functionality of Ribbonsoft dxflib 3.17.0. A specially-crafted .dxf file can lead to a heap buffer overflow. An attacker can provide a malicious file to trigger this vulnerability. Se presenta una vulnerabilidad de ejecución de código en la funcionalidad DL_Dxf::handleLWPolylineData de Ribbonsoft dxflib versión 3.17.0. Un archivo .dxf especialmente diseñado puede conllevar a un desbordamiento del búfer de la pila. • https://lists.debian.org/debian-lts-announce/2022/06/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5BUOTYU3KKIYE4BEBUFA4MRS462P3OWM https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DA4C4X5GMM65VYLUW7Q7YL6P5NDB633A https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/IMGMEPTYL7WTQ333J6SMC6MUHDMMWT3O https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/L2H36XRMAPQBIOVIIFX6KUT5 • CWE-191: Integer Underflow (Wrap or Wraparound) CWE-787: Out-of-bounds Write •
CVSS: 8.8EPSS: 0%CPEs: 15EXPL: 1CVE-2021-3653 – kernel: SVM nested virtualization issue in KVM (AVIC support)
https://notcve.org/view.php?id=CVE-2021-3653
A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7. • http://packetstormsecurity.com/files/165477/Kernel-Live-Patch-Security-Notice-LSN-0083-1.html https://bugzilla.redhat.com/show_bug.cgi?id=1983686 https://lists.debian.org/debian-lts-announce/2021/10/msg00010.html https://lists.debian.org/debian-lts-announce/2021/12/msg00012.html https://www.openwall.com/lists/oss-security/2021/08/16/1 https://access.redhat.com/security/cve/CVE-2021-3653 • CWE-862: Missing Authorization •
