CVE-2017-14491 13 Arista, Arubanetworks, Canonical and 10 more 35 Eos, Arubaos, Ubuntu Linux and 32 more 2025-01-14 9.8 Critical
Heap-based buffer overflow in dnsmasq before 2.78 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a crafted DNS response.
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-2019-9514 13 Apache, Apple, Canonical and 10 more 44 Traffic Server, Mac Os X, Swiftnio and 41 more 2025-01-14 7.5 High
Some HTTP/2 implementations are vulnerable to a reset flood, potentially leading to a denial of service. The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both.
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-2019-9518 11 Apache, Apple, Canonical and 8 more 26 Traffic Server, Mac Os X, Swiftnio and 23 more 2025-01-14 7.5 High
Some HTTP/2 implementations are vulnerable to a flood of empty frames, potentially leading to a denial of service. The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU.
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-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-2019-9516 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2025-01-14 6.5 Medium
Some HTTP/2 implementations are vulnerable to a header leak, potentially leading to a denial of service. The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory.
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-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-2019-9515 12 Apache, Apple, Canonical and 9 more 36 Traffic Server, Mac Os X, Swiftnio and 33 more 2025-01-14 7.5 High
Some HTTP/2 implementations are vulnerable to a settings flood, potentially leading to a denial of service. The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both.
CVE-2017-9117 2 Canonical, Libtiff 2 Ubuntu Linux, Libtiff 2025-01-08 4 Medium
In LibTIFF 4.0.6 and possibly other versions, the program processes BMP images without verifying that biWidth and biHeight in the bitmap-information header match the actual input, as demonstrated by a heap-based buffer over-read in bmp2tiff. NOTE: mentioning bmp2tiff does not imply that the activation point is in the bmp2tiff.c file (which was removed before the 4.0.7 release).
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.
