| CVE-2019-9517 | 12 Apache, Apple, Canonical and 9 more | 28 Http Server, Traffic Server, Mac Os X and 25 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to unconstrained interal data buffering, potentially leading to a denial of service. The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both. | ||||
| CVE-2019-9511 | 12 Apache, Apple, Canonical and 9 more | 29 Traffic Server, Mac Os X, Swiftnio and 26 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both. | ||||
| CVE-2019-19344 | 4 Canonical, Opensuse, Samba and 1 more | 7 Ubuntu Linux, Leap, Samba and 4 more | 2025-01-14 | 6.5 Medium |
| There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while other local variables still point at the original buffer. | ||||
| CVE-2019-14907 | 6 Canonical, Debian, Fedoraproject and 3 more | 10 Ubuntu Linux, Debian Linux, Fedora and 7 more | 2025-01-14 | 6.5 Medium |
| All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with "log level = 3" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless). | ||||
| CVE-2019-9513 | 12 Apache, Apple, Canonical and 9 more | 25 Traffic Server, Mac Os X, Swiftnio and 22 more | 2025-01-14 | 7.5 High |
| Some HTTP/2 implementations are vulnerable to resource loops, potentially leading to a denial of service. The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU. | ||||
| CVE-2018-7185 | 6 Canonical, Hpe, Netapp and 3 more | 23 Ubuntu Linux, Hpux-ntp, Hci and 20 more | 2025-01-14 | 7.5 High |
| The protocol engine in ntp 4.2.6 before 4.2.8p11 allows a remote attackers to cause a denial of service (disruption) by continually sending a packet with a zero-origin timestamp and source IP address of the "other side" of an interleaved association causing the victim ntpd to reset its association. | ||||
| CVE-2018-7184 | 5 Canonical, Netapp, Ntp and 2 more | 10 Ubuntu Linux, Cloud Backup, Steelstore Cloud Integrated Storage and 7 more | 2025-01-14 | N/A |
| ntpd in ntp 4.2.8p4 before 4.2.8p11 drops bad packets before updating the "received" timestamp, which allows remote attackers to cause a denial of service (disruption) by sending a packet with a zero-origin timestamp causing the association to reset and setting the contents of the packet as the most recent timestamp. This issue is a result of an incomplete fix for CVE-2015-7704. | ||||
| CVE-2017-18017 | 9 Arista, Canonical, Debian and 6 more | 33 Eos, Ubuntu Linux, Debian Linux and 30 more | 2025-01-03 | 9.8 Critical |
| The tcpmss_mangle_packet function in net/netfilter/xt_TCPMSS.c in the Linux kernel before 4.11, and 4.9.x before 4.9.36, allows remote attackers to cause a denial of service (use-after-free and memory corruption) or possibly have unspecified other impact by leveraging the presence of xt_TCPMSS in an iptables action. | ||||
| CVE-2024-0115 | 2 Canonical, Nvidia | 3 Ubuntu Linux, Cv-cuda, Jetpack Software Development Kit | 2024-12-26 | 6.1 Medium |
| NVIDIA CV-CUDA for Ubuntu 20.04, Ubuntu 22.04, and Jetpack contains a vulnerability in Python APIs where a user may cause an uncontrolled resource consumption issue by a long running CV-CUDA Python process. A successful exploit of this vulnerability may lead to denial of service and data loss. | ||||
| CVE-2024-6773 | 2 Canonical, Google | 2 Ubuntu Linux, Chrome | 2024-12-26 | 8.8 High |
| Inappropriate implementation in V8 in Google Chrome prior to 126.0.6478.182 allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page. (Chromium security severity: High) | ||||
| CVE-2023-45866 | 7 Apple, Bluproducts, Canonical and 4 more | 17 Ipados, Iphone Os, Iphone Se and 14 more | 2024-12-12 | 6.3 Medium |
| Bluetooth HID Hosts in BlueZ may permit an unauthenticated Peripheral role HID Device to initiate and establish an encrypted connection, and accept HID keyboard reports, potentially permitting injection of HID messages when no user interaction has occurred in the Central role to authorize such access. An example affected package is bluez 5.64-0ubuntu1 in Ubuntu 22.04LTS. NOTE: in some cases, a CVE-2020-0556 mitigation would have already addressed this Bluetooth HID Hosts issue. | ||||
| CVE-2019-12749 | 3 Canonical, Freedesktop, Redhat | 5 Ubuntu Linux, Dbus, Enterprise Linux and 2 more | 2024-12-06 | N/A |
| dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent client connection came from an attacker-chosen uid, allowing authentication bypass. | ||||
| CVE-2018-0202 | 3 Canonical, Clamav, Debian | 3 Ubuntu Linux, Clamav, Debian Linux | 2024-12-02 | N/A |
| clamscan in ClamAV before 0.99.4 contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper input validation checking mechanisms when handling Portable Document Format (.pdf) files sent to an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted .pdf file to an affected device. This action could cause an out-of-bounds read when ClamAV scans the malicious file, allowing the attacker to cause a DoS condition. This concerns pdf_parse_array and pdf_parse_string in libclamav/pdfng.c. Cisco Bug IDs: CSCvh91380, CSCvh91400. | ||||
| CVE-2018-0360 | 3 Canonical, Clamav, Debian | 3 Ubuntu Linux, Clamav, Debian Linux | 2024-11-29 | N/A |
| ClamAV before 0.100.1 has an HWP integer overflow with a resultant infinite loop via a crafted Hangul Word Processor file. This is in parsehwp3_paragraph() in libclamav/hwp.c. | ||||
| CVE-2018-15378 | 3 Canonical, Clamav, Debian | 3 Ubuntu Linux, Clamav, Debian Linux | 2024-11-26 | N/A |
| A vulnerability in ClamAV versions prior to 0.100.2 could allow an attacker to cause a denial of service (DoS) condition. The vulnerability is due to an error related to the MEW unpacker within the "unmew11()" function (libclamav/mew.c), which can be exploited to trigger an invalid read memory access via a specially crafted EXE file. | ||||
| CVE-2020-10108 | 6 Canonical, Debian, Fedoraproject and 3 more | 7 Ubuntu Linux, Debian Linux, Fedora and 4 more | 2024-11-25 | 9.8 Critical |
| In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with two content-length headers, it ignored the first header. When the second content-length value was set to zero, the request body was interpreted as a pipelined request. | ||||
| CVE-2020-10109 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-25 | 9.8 Critical |
| In Twisted Web through 19.10.0, there was an HTTP request splitting vulnerability. When presented with a content-length and a chunked encoding header, the content-length took precedence and the remainder of the request body was interpreted as a pipelined request. | ||||
| CVE-2019-12387 | 5 Canonical, Fedoraproject, Oracle and 2 more | 8 Ubuntu Linux, Fedora, Solaris and 5 more | 2024-11-25 | 6.1 Medium |
| In Twisted before 19.2.1, twisted.web did not validate or sanitize URIs or HTTP methods, allowing an attacker to inject invalid characters such as CRLF. | ||||
| CVE-2024-0093 | 5 Canonical, Citrix, Nvidia and 2 more | 6 Ubuntu Linux, Hypervisor, Cloud Gaming and 3 more | 2024-11-21 | 6.5 Medium |
| NVIDIA GPU software for Linux contains a vulnerability where it can expose sensitive information to an actor that is not explicitly authorized to have access to that information. A successful exploit of this vulnerability might lead to information disclosure. | ||||
| CVE-2024-0092 | 6 Canonical, Citrix, Microsoft and 3 more | 14 Ubuntu Linux, Hypervisor, Azure Stack Hci and 11 more | 2024-11-21 | 5.5 Medium |
| NVIDIA GPU Driver for Windows and Linux contains a vulnerability where an improper check or improper handling of exception conditions might lead to denial of service. | ||||
