https://notcve.org/view.php?id=CVE-2021-3527
A flaw was found in the USB redirector device (usb-redir) of QEMU. Small USB packets are combined into a single, large transfer request, to reduce the overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array (VLA) on the stack without proper validation. Since the total size is not bounded, a malicious guest could use this flaw to influence the array length and cause the QEMU process to perform an excessive allocation on the stack, resulting in a denial of service. Se encontró un fallo en el dispositivo redirector USB (usb-redir) de QEMU. • https://bugzilla.redhat.com/show_bug.cgi?id=1955695 https://gitlab.com/qemu-project/qemu/-/commit/05a40b172e4d691371534828078be47e7fff524c https://gitlab.com/qemu-project/qemu/-/commit/7ec54f9eb62b5d177e30eb8b1cad795a5f8d8986 https://lists.debian.org/debian-lts-announce/2021/09/msg00000.html https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html https://security.gentoo.org/glsa/202208-27 https://security.netapp.com/advisory/ntap-20210708-0008 https://www.openwall.com/lists/oss-security/ • CWE-770: Allocation of Resources Without Limits or Throttling •
