CVE-2019-9514 13 Apache, Apple, Canonical and 10 more 30 Traffic Server, Mac Os X, Swiftnio and 27 more 2025-01-14 7.8 HIGH 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-2019-9516 12 Apache, Apple, Canonical and 9 more 21 Traffic Server, Mac Os X, Swiftnio and 18 more 2025-01-14 6.8 MEDIUM 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-2019-9518 11 Apache, Apple, Canonical and 8 more 20 Traffic Server, Mac Os X, Swiftnio and 17 more 2025-01-14 7.8 HIGH 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 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2025-01-14 7.8 HIGH 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-2019-14907 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2025-01-14 2.6 LOW 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-2019-9515 12 Apache, Apple, Canonical and 9 more 24 Traffic Server, Mac Os X, Swiftnio and 21 more 2025-01-14 7.8 HIGH 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-2019-9511 12 Apache, Apple, Canonical and 9 more 22 Traffic Server, Mac Os X, Swiftnio and 19 more 2025-01-14 7.8 HIGH 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-2019-9517 12 Apache, Apple, Canonical and 9 more 25 Http Server, Traffic Server, Mac Os X and 22 more 2025-01-14 7.8 HIGH 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-2023-34152 3 Fedoraproject, Imagemagick, Redhat 4 Extra Packages For Enterprise Linux, Fedora, Imagemagick and 1 more 2025-01-13 N/A 9.8 CRITICAL
A vulnerability was found in ImageMagick. This security flaw cause a remote code execution vulnerability in OpenBlob with --enable-pipes configured.
CVE-2023-2953 4 Apple, Netapp, Openldap and 1 more 16 Macos, Active Iq Unified Manager, Clustered Data Ontap and 13 more 2025-01-10 N/A 7.5 HIGH
A vulnerability was found in openldap. This security flaw causes a null pointer dereference in ber_memalloc_x() function.
CVE-2023-34153 3 Fedoraproject, Imagemagick, Redhat 4 Extra Packages For Enterprise Linux, Fedora, Imagemagick and 1 more 2025-01-10 N/A 7.8 HIGH
A vulnerability was found in ImageMagick. This security flaw causes a shell command injection vulnerability via video:vsync or video:pixel-format options in VIDEO encoding/decoding.
CVE-2023-2977 2 Opensc Project, Redhat 2 Opensc, Enterprise Linux 2025-01-09 N/A 7.1 HIGH
A vulnerbility was found in OpenSC. This security flaw cause a buffer overrun vulnerability in pkcs15 cardos_have_verifyrc_package. The attacker can supply a smart card package with malformed ASN1 context. The cardos_have_verifyrc_package function scans the ASN1 buffer for 2 tags, where remaining length is wrongly caculated due to moved starting pointer. This leads to possible heap-based buffer oob read. In cases where ASAN is enabled while compiling this causes a crash. Further info leak or more damage is possible.
CVE-2023-2455 3 Fedoraproject, Postgresql, Redhat 4 Fedora, Postgresql, Enterprise Linux and 1 more 2025-01-06 N/A 5.4 MEDIUM
Row security policies disregard user ID changes after inlining; PostgreSQL could permit incorrect policies to be applied in certain cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy.
CVE-2023-2454 3 Fedoraproject, Postgresql, Redhat 4 Fedora, Postgresql, Enterprise Linux and 1 more 2025-01-06 N/A 7.2 HIGH
schema_element defeats protective search_path changes; It was found that certain database calls in PostgreSQL could permit an authed attacker with elevated database-level privileges to execute arbitrary code.
CVE-2024-3056 3 Fedoraproject, Podman Project, Redhat 4 Fedora, Podman, Enterprise Linux and 1 more 2024-12-27 N/A 7.7 HIGH
A flaw was found in Podman. This issue may allow an attacker to create a specially crafted container that, when configured to share the same IPC with at least one other container, can create a large number of IPC resources in /dev/shm. The malicious container will continue to exhaust resources until it is out-of-memory (OOM) killed. While the malicious container's cgroup will be removed, the IPC resources it created are not. Those resources are tied to the IPC namespace that will not be removed until all containers using it are stopped, and one non-malicious container is holding the namespace open. The malicious container is restarted, either automatically or by attacker control, repeating the process and increasing the amount of memory consumed. With a container configured to restart always, such as `podman run --restart=always`, this can result in a memory-based denial of service of the system.
CVE-2018-12121 2 Nodejs, Redhat 8 Node.js, Enterprise Linux, Enterprise Linux Desktop and 5 more 2024-12-27 5.0 MEDIUM 7.5 HIGH
Node.js: All versions prior to Node.js 6.15.0, 8.14.0, 10.14.0 and 11.3.0: Denial of Service with large HTTP headers: By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.
CVE-2024-10041 2 Linux-pam, Redhat 2 Linux-pam, Enterprise Linux 2024-12-18 N/A 4.7 MEDIUM
A vulnerability was found in PAM. The secret information is stored in memory, where the attacker can trigger the victim program to execute by sending characters to its standard input (stdin). As this occurs, the attacker can train the branch predictor to execute an ROP chain speculatively. This flaw could result in leaked passwords, such as those found in /etc/shadow while performing authentications.
CVE-2023-46846 2 Redhat, Squid-cache 8 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 5 more 2024-12-18 N/A 9.3 CRITICAL
SQUID is vulnerable to HTTP request smuggling, caused by chunked decoder lenience, allows a remote attacker to perform Request/Response smuggling past firewall and frontend security systems.
CVE-2022-1949 2 Fedoraproject, Redhat 4 Fedora, 389 Directory Server, Directory Server and 1 more 2024-12-13 5.0 MEDIUM 7.5 HIGH
An access control bypass vulnerability found in 389-ds-base. That mishandling of the filter that would yield incorrect results, but as that has progressed, can be determined that it actually is an access control bypass. This may allow any remote unauthenticated user to issue a filter that allows searching for database items they do not have access to, including but not limited to potentially userPassword hashes and other sensitive data.
CVE-2024-9341 2 Containers, Redhat 3 Common, Enterprise Linux, Openshift Container Platform 2024-12-11 N/A 5.4 MEDIUM
A flaw was found in Go. When FIPS mode is enabled on a system, container runtimes may incorrectly handle certain file paths due to improper validation in the containers/common Go library. This flaw allows an attacker to exploit symbolic links and trick the system into mounting sensitive host directories inside a container. This issue also allows attackers to access critical host files, bypassing the intended isolation between containers and the host system.
