Quick Emulator (Qemu) built with the USB EHCI Emulation support is vulnerable to a memory leakage issue. It could occur while processing packet data in 'ehci_init_transfer'. A guest user/process could use this issue to leak host memory, resulting in DoS for a host. | ||||
CVE-2016-9921 | 3 Debian, Qemu, Redhat | 5 Debian Linux, Qemu, Enterprise Linux and 2 more | 2025-04-12 | 6.5 Medium |
Quick emulator (Qemu) built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to a divide by zero issue. It could occur while copying VGA data when cirrus graphics mode was set to be VGA. A privileged user inside guest could use this flaw to crash the Qemu process instance on the host, resulting in DoS. | ||||
CVE-2016-6835 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-12 | 6.0 Medium |
The vmxnet_tx_pkt_parse_headers function in hw/net/vmxnet_tx_pkt.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (buffer over-read) by leveraging failure to check IP header length. | ||||
CVE-2015-3214 | 6 Arista, Debian, Lenovo and 3 more | 20 Eos, Debian Linux, Emc Px12-400r Ivx and 17 more | 2025-04-12 | N/A |
The pit_ioport_read in i8254.c in the Linux kernel before 2.6.33 and QEMU before 2.3.1 does not distinguish between read lengths and write lengths, which might allow guest OS users to execute arbitrary code on the host OS by triggering use of an invalid index. | ||||
CVE-2016-8576 | 4 Debian, Opensuse, Qemu and 1 more | 6 Debian Linux, Leap, Qemu and 3 more | 2025-04-12 | 6.0 Medium |
The xhci_ring_fetch function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator) allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) by leveraging failure to limit the number of link Transfer Request Blocks (TRB) to process. | ||||

GNU Bash through 4.3 bash43-025 processes trailing strings after certain malformed function definitions in the values of environment variables, which allows remote attackers to write to files or possibly have unknown other impact via a crafted environment, as demonstrated by vectors involving the ForceCommand feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server, scripts executed by unspecified DHCP clients, and other situations in which setting the environment occurs across a privilege boundary from Bash execution. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-6271. | ||||
CVE-2014-3469 | 4 Debian, Gnu, Redhat and 1 more | 15 Debian Linux, Gnutls, Libtasn1 and 12 more | 2025-04-12 | N/A |
The (1) asn1_read_value_type and (2) asn1_read_value functions in GNU Libtasn1 before 3.6 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and crash) via a NULL value in an ivalue argument. | ||||

CVE-2009-4272 | 2 Linux, Redhat | 7 Linux Kernel, Enterprise Linux, Enterprise Linux Desktop and 4 more | 2025-04-11 | 7.5 High |
A certain Red Hat patch for net/ipv4/route.c in the Linux kernel 2.6.18 on Red Hat Enterprise Linux (RHEL) 5 allows remote attackers to cause a denial of service (deadlock) via crafted packets that force collisions in the IPv4 routing hash table, and trigger a routing "emergency" in which a hash chain is too long. NOTE: this is related to an issue in the Linux kernel before 2.6.31, when the kernel routing cache is disabled, involving an uninitialized pointer and a panic. | ||||
CVE-2012-3515 | 7 Canonical, Debian, Opensuse and 4 more | 15 Ubuntu Linux, Debian Linux, Opensuse and 12 more | 2025-04-11 | N/A |
