CVE-2023-50387 8 Fedoraproject, Isc, Microsoft and 5 more 13 Fedora, Bind, Windows Server 2008 and 10 more 2025-05-12 N/A 7.5 HIGH
Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.
CVE-2023-46841 2 Fedoraproject, Xen 2 Fedora, Xen 2025-05-12 N/A 6.5 MEDIUM
Recent x86 CPUs offer functionality named Control-flow Enforcement Technology (CET). A sub-feature of this are Shadow Stacks (CET-SS). CET-SS is a hardware feature designed to protect against Return Oriented Programming attacks. When enabled, traditional stacks holding both data and return addresses are accompanied by so called "shadow stacks", holding little more than return addresses. Shadow stacks aren't writable by normal instructions, and upon function returns their contents are used to check for possible manipulation of a return address coming from the traditional stack. In particular certain memory accesses need intercepting by Xen. In various cases the necessary emulation involves kind of replaying of the instruction. Such replaying typically involves filling and then invoking of a stub. Such a replayed instruction may raise an exceptions, which is expected and dealt with accordingly. Unfortunately the interaction of both of the above wasn't right: Recovery involves removal of a call frame from the (traditional) stack. The counterpart of this operation for the shadow stack was missing.
CVE-2024-27507 2 Fedoraproject, Liblas 2 Fedora, Liblas 2025-05-12 N/A 7.5 HIGH
libLAS 1.8.1 contains a memory leak vulnerability in /libLAS/apps/ts2las.cpp.
CVE-2021-28831 3 Busybox, Debian, Fedoraproject 3 Busybox, Debian Linux, Fedora 2025-05-09 5.0 MEDIUM 7.5 HIGH
decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data.
CVE-2021-26937 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Screen 2025-05-09 7.5 HIGH 9.8 CRITICAL
encoding.c in GNU Screen through 4.8.0 allows remote attackers to cause a denial of service (invalid write access and application crash) or possibly have unspecified other impact via a crafted UTF-8 character sequence.
CVE-2024-1059 2 Fedoraproject, Google 2 Fedora, Chrome 2025-05-08 N/A 8.8 HIGH
Use after free in Peer Connection in Google Chrome prior to 121.0.6167.139 allowed a remote attacker to potentially exploit stack corruption via a crafted HTML page. (Chromium security severity: High)
CVE-2023-32006 2 Fedoraproject, Nodejs 2 Fedora, Node.js 2025-05-08 N/A 8.8 HIGH
The use of `module.constructor.createRequire()` can bypass the policy mechanism and require modules outside of the policy.json definition for a given module. This vulnerability affects all users using the experimental policy mechanism in all active release lines: 16.x, 18.x, and, 20.x. Please note that at the time this CVE was issued, the policy is an experimental feature of Node.js.
CVE-2023-32004 2 Fedoraproject, Nodejs 2 Fedora, Node.js 2025-05-08 N/A 8.8 HIGH
A vulnerability has been discovered in Node.js version 20, specifically within the experimental permission model. This flaw relates to improper handling of Buffers in file system APIs causing a traversal path to bypass when verifying file permissions. This vulnerability affects all users using the experimental permission model in Node.js 20. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
CVE-2022-37454 8 Debian, Extended Keccak Code Package Project, Fedoraproject and 5 more 8 Debian Linux, Extended Keccak Code Package, Fedora and 5 more 2025-05-08 N/A 9.8 CRITICAL
The Keccak XKCP SHA-3 reference implementation before fdc6fef has an integer overflow and resultant buffer overflow that allows attackers to execute arbitrary code or eliminate expected cryptographic properties. This occurs in the sponge function interface.
CVE-2021-46848 3 Debian, Fedoraproject, Gnu 3 Debian Linux, Fedora, Libtasn1 2025-05-07 N/A 9.1 CRITICAL
GNU Libtasn1 before 4.19.0 has an ETYPE_OK off-by-one array size check that affects asn1_encode_simple_der.
CVE-2022-42915 5 Apple, Fedoraproject, Haxx and 2 more 13 Macos, Fedora, Curl and 10 more 2025-05-07 N/A 8.1 HIGH
curl before 7.86.0 has a double free. If curl is told to use an HTTP proxy for a transfer with a non-HTTP(S) URL, it sets up the connection to the remote server by issuing a CONNECT request to the proxy, and then tunnels the rest of the protocol through. An HTTP proxy might refuse this request (HTTP proxies often only allow outgoing connections to specific port numbers, like 443 for HTTPS) and instead return a non-200 status code to the client. Due to flaws in the error/cleanup handling, this could trigger a double free in curl if one of the following schemes were used in the URL for the transfer: dict, gopher, gophers, ldap, ldaps, rtmp, rtmps, or telnet. The earliest affected version is 7.77.0.
CVE-2022-25600 2 Fedoraproject, Weplugins 2 Fedora, Wp Maps 2025-05-07 6.8 MEDIUM 5.4 MEDIUM
Cross-Site Request Forgery (CSRF) vulnerability affecting Delete Marker Category, Delete Map, and Copy Map functions in WP Google Map plugin (versions <= 4.2.3).
CVE-2023-4911 6 Canonical, Debian, Fedoraproject and 3 more 38 Ubuntu Linux, Debian Linux, Fedora and 35 more 2025-05-06 N/A 7.8 HIGH
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2022-40617 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2025-05-06 N/A 7.5 HIGH
strongSwan before 5.9.8 allows remote attackers to cause a denial of service in the revocation plugin by sending a crafted end-entity (and intermediate CA) certificate that contains a CRL/OCSP URL that points to a server (under the attacker's control) that doesn't properly respond but (for example) just does nothing after the initial TCP handshake, or sends an excessive amount of application data.
CVE-2022-42315 3 Debian, Fedoraproject, Xen 3 Debian Linux, Fedora, Xen 2025-05-06 N/A 6.5 MEDIUM
Xenstore: guests can let run xenstored out of memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction

CVE-2018-25032 11 Apple, Azul, Debian and 8 more 38 Mac Os X, Macos, Zulu and 35 more 2025-05-06 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.
CVE-2023-6693 3 Fedoraproject, Qemu, Redhat 3 Fedora, Qemu, Enterprise Linux 2025-05-06 N/A 4.9 MEDIUM
A stack based buffer overflow was found in the virtio-net device of QEMU. This issue occurs when flushing TX in the virtio_net_flush_tx function if guest features VIRTIO_NET_F_HASH_REPORT, VIRTIO_F_VERSION_1 and VIRTIO_NET_F_MRG_RXBUF are enabled. This could allow a malicious user to overwrite local variables allocated on the stack. Specifically, the `out_sg` variable could be used to read a part of process memory and send it to the wire, causing an information leak.
