| CVE-2025-46421 | 1 Redhat | 5 Enterprise Linux, Rhel Aus, Rhel E4s and 2 more | 2026-04-15 | 6.8 Medium |
| A flaw was found in libsoup. When libsoup clients encounter an HTTP redirect, they mistakenly send the HTTP Authorization header to the new host that the redirection points to. This allows the new host to impersonate the user to the original host that issued the redirect. | ||||
| CVE-2023-4727 | 1 Redhat | 6 Certificate System Eus, Enterprise Linux, Rhel Aus and 3 more | 2026-04-15 | 7.5 High |
| A flaw was found in dogtag-pki and pki-core. The token authentication scheme can be bypassed with a LDAP injection. By passing the query string parameter sessionID=*, an attacker can authenticate with an existing session saved in the LDAP directory server, which may lead to escalation of privilege. | ||||
| CVE-2024-30156 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-04-15 | 7.5 High |
| Varnish Cache before 7.3.2 and 7.4.x before 7.4.3 (and before 6.0.13 LTS), and Varnish Enterprise 6 before 6.0.12r6, allows credits exhaustion for an HTTP/2 connection control flow window, aka a Broke Window Attack. | ||||
| CVE-2023-6597 | 2 Python Software Foundation, Redhat | 8 Cpython, Enterprise Linux, Openshift and 5 more | 2026-04-15 | 7.8 High |
| An issue was found in the CPython `tempfile.TemporaryDirectory` class affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The tempfile.TemporaryDirectory class would dereference symlinks during cleanup of permissions-related errors. This means users which can run privileged programs are potentially able to modify permissions of files referenced by symlinks in some circumstances. | ||||
| CVE-2024-1737 | 2 Isc, Redhat | 8 Bind, Enterprise Linux, Openshift and 5 more | 2026-04-15 | 7.5 High |
| Resolver caches and authoritative zone databases that hold significant numbers of RRs for the same hostname (of any RTYPE) can suffer from degraded performance as content is being added or updated, and also when handling client queries for this name. This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.27, 9.19.0 through 9.19.24, 9.11.4-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.27-S1. | ||||
| CVE-2024-23184 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 5 Medium |
| Having a large number of address headers (From, To, Cc, Bcc, etc.) becomes excessively CPU intensive. With 100k header lines CPU usage is already 12 seconds, and in a production environment we observed 500k header lines taking 18 minutes to parse. Since this can be triggered by external actors sending emails to a victim, this is a security issue. An external attacker can send specially crafted messages that consume target system resources and cause outage. One can implement restrictions on address headers on MTA component preceding Dovecot. No publicly available exploits are known. | ||||
| CVE-2023-45288 | 3 Go Standard Library, Golang, Redhat | 33 Net\/http, Http2, Acm and 30 more | 2026-04-15 | 7.5 High |
| An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection. | ||||
| CVE-2025-29786 | 1 Redhat | 5 Enterprise Linux, Openshift Custom Metrics Autoscaler, Openshift Distributed Tracing and 2 more | 2026-04-15 | 7.5 High |
| Expr is an expression language and expression evaluation for Go. Prior to version 1.17.0, if the Expr expression parser is given an unbounded input string, it will attempt to compile the entire string and generate an Abstract Syntax Tree (AST) node for each part of the expression. In scenarios where input size isn’t limited, a malicious or inadvertent extremely large expression can consume excessive memory as the parser builds a huge AST. This can ultimately lead to*excessive memory usage and an Out-Of-Memory (OOM) crash of the process. This issue is relatively uncommon and will only manifest when there are no restrictions on the input size, i.e. the expression length is allowed to grow arbitrarily large. In typical use cases where inputs are bounded or validated, this problem would not occur. The problem has been patched in the latest versions of the Expr library. The fix introduces compile-time limits on the number of AST nodes and memory usage during parsing, preventing any single expression from exhausting resources. Users should upgrade to Expr version 1.17.0 or later, as this release includes the new node budget and memory limit safeguards. Upgrading to v1.17.0 ensures that extremely deep or large expressions are detected and safely aborted during compilation, avoiding the OOM condition. For users who cannot immediately upgrade, the recommended workaround is to impose an input size restriction before parsing. In practice, this means validating or limiting the length of expression strings that your application will accept. For example, set a maximum allowable number of characters (or nodes) for any expression and reject or truncate inputs that exceed this limit. By ensuring no unbounded-length expression is ever fed into the parser, one can prevent the parser from constructing a pathologically large AST and avoid potential memory exhaustion. In short, pre-validate and cap input size as a safeguard in the absence of the patch. | ||||
| CVE-2024-5953 | 1 Redhat | 6 Directory Server, Directory Server E4s, Directory Server Eus and 3 more | 2026-04-15 | 5.7 Medium |
| A denial of service vulnerability was found in the 389-ds-base LDAP server. This issue may allow an authenticated user to cause a server denial of service while attempting to log in with a user with a malformed hash in their password. | ||||
| CVE-2024-2199 | 1 Redhat | 4 Directory Server, Directory Server E4s, Enterprise Linux and 1 more | 2026-04-15 | 5.7 Medium |
| A denial of service vulnerability was found in 389-ds-base ldap server. This issue may allow an authenticated user to cause a server crash while modifying `userPassword` using malformed input. | ||||
| CVE-2024-0450 | 2 Python, Redhat | 7 Cpython, Enterprise Linux, Rhel Aus and 4 more | 2026-04-15 | 6.2 Medium |
| An issue was found in the CPython `zipfile` module affecting versions 3.12.1, 3.11.7, 3.10.13, 3.9.18, and 3.8.18 and prior. The zipfile module is vulnerable to “quoted-overlap” zip-bombs which exploit the zip format to create a zip-bomb with a high compression ratio. The fixed versions of CPython makes the zipfile module reject zip archives which overlap entries in the archive. | ||||
| CVE-2024-23185 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 7.5 High |
| Very large headers can cause resource exhaustion when parsing message. The message-parser normally reads reasonably sized chunks of the message. However, when it feeds them to message-header-parser, it starts building up "full_value" buffer out of the smaller chunks. The full_value buffer has no size limit, so large headers can cause large memory usage. It doesn't matter whether it's a single long header line, or a single header split into multiple lines. This bug exists in all Dovecot versions. Incoming mails typically have some size limits set by MTA, so even largest possible header size may still fit into Dovecot's vsz_limit. So attackers probably can't DoS a victim user this way. A user could APPEND larger mails though, allowing them to DoS themselves (although maybe cause some memory issues for the backend in general). One can implement restrictions on headers on MTA component preceding Dovecot. No publicly available exploits are known. | ||||
| CVE-2025-32907 | 1 Redhat | 3 Enterprise Linux, Rhel E4s, Rhel Eus | 2026-04-15 | 5.3 Medium |
| A flaw was found in libsoup. The implementation of HTTP range requests is vulnerable to a resource consumption attack. This flaw allows a malicious client to request the same range many times in a single HTTP request, causing the server to use large amounts of memory. This does not allow for a full denial of service. | ||||
| CVE-2025-32906 | 1 Redhat | 6 Enterprise Linux, Rhel Aus, Rhel E4s and 3 more | 2026-04-15 | 7.5 High |
| A flaw was found in libsoup, where the soup_headers_parse_request() function may be vulnerable to an out-of-bound read. This flaw allows a malicious user to use a specially crafted HTTP request to crash the HTTP server. | ||||
| CVE-2024-11187 | 1 Redhat | 8 Enterprise Linux, Openshift, Openshift Ai and 5 more | 2026-04-15 | 7.5 High |
| It is possible to construct a zone such that some queries to it will generate responses containing numerous records in the Additional section. An attacker sending many such queries can cause either the authoritative server itself or an independent resolver to use disproportionate resources processing the queries. Zones will usually need to have been deliberately crafted to attack this exposure. This issue affects BIND 9 versions 9.11.0 through 9.11.37, 9.16.0 through 9.16.50, 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, 9.11.3-S1 through 9.11.37-S1, 9.16.8-S1 through 9.16.50-S1, and 9.18.11-S1 through 9.18.32-S1. | ||||
| CVE-2025-1244 | 1 Redhat | 7 Enterprise Linux, Openshift Builds, Rhel Aus and 4 more | 2026-04-15 | 8.8 High |
| A command injection flaw was found in the text editor Emacs. It could allow a remote, unauthenticated attacker to execute arbitrary shell commands on a vulnerable system. Exploitation is possible by tricking users into visiting a specially crafted website or an HTTP URL with a redirect. | ||||
| CVE-2023-28746 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 6.5 Medium |
| Information exposure through microarchitectural state after transient execution from some register files for some Intel(R) Atom(R) Processors may allow an authenticated user to potentially enable information disclosure via local access. | ||||
| CVE-2025-6032 | 1 Redhat | 3 Enterprise Linux, Openshift, Rhel Eus | 2026-04-15 | 8.3 High |
| A flaw was found in Podman. The podman machine init command fails to verify the TLS certificate when downloading the VM images from an OCI registry. This issue results in a Man In The Middle attack. | ||||
| CVE-2025-32053 | 1 Redhat | 2 Enterprise Linux, Rhel Eus | 2026-04-15 | 6.5 Medium |
| A flaw was found in libsoup. A vulnerability in sniff_feed_or_html() and skip_insignificant_space() functions may lead to a heap buffer over-read. | ||||
| CVE-2024-37298 | 2 Gorillatoolkit, Redhat | 6 Schema, Advanced Cluster Security, Enterprise Linux and 3 more | 2026-04-15 | 7.5 High |
| gorilla/schema converts structs to and from form values. Prior to version 1.4.1 Running `schema.Decoder.Decode()` on a struct that has a field of type `[]struct{...}` opens it up to malicious attacks regarding memory allocations, taking advantage of the sparse slice functionality. Any use of `schema.Decoder.Decode()` on a struct with arrays of other structs could be vulnerable to this memory exhaustion vulnerability. Version 1.4.1 contains a patch for the issue. | ||||
