CVE-2023-4806 3 Fedoraproject, Gnu, Redhat 22 Fedora, Glibc, Codeready Linux Builder Eus and 19 more 2025-09-26 N/A 5.9 MEDIUM
A flaw has been identified in glibc. In an extremely rare situation, the getaddrinfo function may access memory that has been freed, resulting in an application crash. This issue is only exploitable when a NSS module implements only the _nss_*_gethostbyname2_r and _nss_*_getcanonname_r hooks without implementing the _nss_*_gethostbyname3_r hook. The resolved name should return a large number of IPv6 and IPv4, and the call to the getaddrinfo function should have the AF_INET6 address family with AI_CANONNAME, AI_ALL and AI_V4MAPPED as flags.
CVE-2023-51767 3 Fedoraproject, Openbsd, Redhat 3 Fedora, Openssh, Enterprise Linux 2025-09-22 N/A 7.0 HIGH
OpenSSH through 10.0, when common types of DRAM are used, might allow row hammer attacks (for authentication bypass) because the integer value of authenticated in mm_answer_authpassword does not resist flips of a single bit. NOTE: this is applicable to a certain threat model of attacker-victim co-location in which the attacker has user privileges. NOTE: this is disputed by the Supplier, who states "we do not consider it to be the application's responsibility to defend against platform architectural weaknesses."
CVE-2024-2044 2 Fedoraproject, Pgadmin 2 Fedora, Pgadmin 4 2025-09-19 N/A 9.9 CRITICAL
pgAdmin <= 8.3 is affected by a path-traversal vulnerability while deserializing users’ sessions in the session handling code. If the server is running on Windows, an unauthenticated attacker can load and deserialize remote pickle objects and gain code execution. If the server is running on POSIX/Linux, an authenticated attacker can upload pickle objects, deserialize them, and gain code execution.
CVE-2024-4215 2 Fedoraproject, Pgadmin 2 Fedora, Pgadmin 4 2025-09-19 N/A 7.4 HIGH
pgAdmin <= 8.5 is affected by a multi-factor authentication bypass vulnerability. This vulnerability allows an attacker with knowledge of a legitimate account’s username and password may authenticate to the application and perform sensitive actions within the application, such as managing files and executing SQL queries, regardless of the account’s MFA enrollment status.
CVE-2024-4216 2 Fedoraproject, Pgadmin 2 Fedora, Pgadmin 4 2025-09-19 N/A 7.4 HIGH
pgAdmin <= 8.5 is affected by XSS vulnerability in /settings/store API response json payload. This vulnerability allows attackers to execute malicious script at the client end.
CVE-2024-25713 2 Fedoraproject, Ibireme 2 Fedora, Yyjson 2025-09-17 N/A 8.6 HIGH
yyjson through 0.8.0 has a double free, leading to remote code execution in some cases, because the pool_free function lacks loop checks. (pool_free is part of the pool series allocator, along with pool_malloc and pool_realloc.)
CVE-2021-37150 3 Apache, Debian, Fedoraproject 3 Traffic Server, Debian Linux, Fedora 2025-09-08 N/A 7.5 HIGH
Improper Input Validation vulnerability in header parsing of Apache Traffic Server allows an attacker to request secure resources. This issue affects Apache Traffic Server 8.0.0 to 9.1.2.
CVE-2019-5427 3 Fedoraproject, Mchange, Oracle 11 Fedora, C3p0, Communications Ip Service Activator and 8 more 2025-09-05 5.0 MEDIUM 7.5 HIGH
c3p0 version < 0.9.5.4 may be exploited by a billion laughs attack when loading XML configuration due to missing protections against recursive entity expansion when loading configuration.
CVE-2024-28182 3 Debian, Fedoraproject, Nghttp2 3 Debian Linux, Fedora, Nghttp2 2025-09-02 N/A 5.3 MEDIUM
nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability.
CVE-2023-6270 3 Debian, Fedoraproject, Linux 3 Debian Linux, Fedora, Linux Kernel 2025-08-30 N/A 7.0 HIGH
A flaw was found in the ATA over Ethernet (AoE) driver in the Linux kernel. The aoecmd_cfg_pkts() function improperly updates the refcnt on `struct net_device`, and a use-after-free can be triggered by racing between the free on the struct and the access through the `skbtxq` global queue. This could lead to a denial of service condition or potential code execution.
CVE-2023-1393 2 Fedoraproject, X.org 2 Fedora, X Server 2025-08-29 N/A 7.8 HIGH
A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.
CVE-2024-0408 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2025-08-29 N/A 5.5 MEDIUM
A flaw was found in the X.Org server. The GLX PBuffer code does not call the XACE hook when creating the buffer, leaving it unlabeled. When the client issues another request to access that resource (as with a GetGeometry) or when it creates another resource that needs to access that buffer, such as a GC, the XSELINUX code will try to use an object that was never labeled and crash because the SID is NULL.
CVE-2022-4283 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Enterprise Linux and 1 more 2025-08-29 N/A 7.8 HIGH
A vulnerability was found in X.Org. This security flaw occurs because the XkbCopyNames function left a dangling pointer to freed memory, resulting in out-of-bounds memory access on subsequent XkbGetKbdByName requests.. This issue can lead to local privileges elevation on systems where the X server is running privileged and remote code execution for ssh X forwarding sessions.
CVE-2023-6816 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux Desktop and 4 more 2025-08-29 N/A 9.8 CRITICAL
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.
CVE-2024-0409 4 Fedoraproject, Redhat, Tigervnc and 1 more 12 Fedora, Enterprise Linux, Enterprise Linux Desktop and 9 more 2025-08-29 N/A 7.8 HIGH
A flaw was found in the X.Org server. The cursor code in both Xephyr and Xwayland uses the wrong type of private at creation. It uses the cursor bits type with the cursor as private, and when initiating the cursor, that overwrites the XSELINUX context.
CVE-2024-31208 2 Fedoraproject, Matrix 2 Fedora, Synapse 2025-08-26 N/A 6.5 MEDIUM
Synapse is an open-source Matrix homeserver. A remote Matrix user with malicious intent, sharing a room with Synapse instances before 1.105.1, can dispatch specially crafted events to exploit a weakness in the V2 state resolution algorithm. This can induce high CPU consumption and accumulate excessive data in the database of such instances, resulting in a denial of service. Servers in private federations, or those that do not federate, are not affected. Server administrators should upgrade to 1.105.1 or later. Some workarounds are available. One can ban the malicious users or ACL block servers from the rooms and/or leave the room and purge the room using the admin API.
CVE-2024-4140 2 Fedoraproject, Rjbs 2 Fedora, Email-mime 2025-08-26 N/A 7.5 HIGH
An excessive memory use issue (CWE-770) exists in Email-MIME, before version 1.954, which can cause denial of service when parsing multipart MIME messages. The patch set (from 2020 and 2024) limits excessive depth and the total number of parts.
CVE-2023-45802 3 Apache, Debian, Fedoraproject 3 Http Server, Debian Linux, Fedora 2025-08-25 N/A 5.9 MEDIUM
When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that. This was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) with their own test client. During "normal" HTTP/2 use, the probability to hit this bug is very low. The kept memory would not become noticeable before the connection closes or times out. Users are recommended to upgrade to version 2.4.58, which fixes the issue.
CVE-2023-47212 2 Fedoraproject, Nothings 2 Fedora, Stb Vorbis.c 2025-08-22 N/A 9.8 CRITICAL
A heap-based buffer overflow vulnerability exists in the comment functionality of stb _vorbis.c v1.22. A specially crafted .ogg file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability.
CVE-2018-25032 12 Apple, Azul, Debian and 9 more 39 Mac Os X, Macos, Zulu and 36 more 2025-08-21 5.0 MEDIUM 7.5 HIGH
zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.
