| CVE-2022-21698 | 4 Fedoraproject, Prometheus, Rdo Project and 1 more | 17 Extra Packages For Enterprise Linux, Fedora, Client Golang and 14 more | 2025-04-23 | 7.5 High |
| client_golang is the instrumentation library for Go applications in Prometheus, and the promhttp package in client_golang provides tooling around HTTP servers and clients. In client_golang prior to version 1.11.1, HTTP server is susceptible to a Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods. In order to be affected, an instrumented software must use any of `promhttp.InstrumentHandler*` middleware except `RequestsInFlight`; not filter any specific methods (e.g GET) before middleware; pass metric with `method` label name to our middleware; and not have any firewall/LB/proxy that filters away requests with unknown `method`. client_golang version 1.11.1 contains a patch for this issue. Several workarounds are available, including removing the `method` label name from counter/gauge used in the InstrumentHandler; turning off affected promhttp handlers; adding custom middleware before promhttp handler that will sanitize the request method given by Go http.Request; and using a reverse proxy or web application firewall, configured to only allow a limited set of methods. | ||||
| CVE-2022-24761 | 3 Agendaless, Debian, Redhat | 3 Waitress, Debian Linux, Openstack | 2025-04-23 | 7.5 High |
| Waitress is a Web Server Gateway Interface server for Python 2 and 3. When using Waitress versions 2.1.0 and prior behind a proxy that does not properly validate the incoming HTTP request matches the RFC7230 standard, Waitress and the frontend proxy may disagree on where one request starts and where it ends. This would allow requests to be smuggled via the front-end proxy to waitress and later behavior. There are two classes of vulnerability that may lead to request smuggling that are addressed by this advisory: The use of Python's `int()` to parse strings into integers, leading to `+10` to be parsed as `10`, or `0x01` to be parsed as `1`, where as the standard specifies that the string should contain only digits or hex digits; and Waitress does not support chunk extensions, however it was discarding them without validating that they did not contain illegal characters. This vulnerability has been patched in Waitress 2.1.1. A workaround is available. When deploying a proxy in front of waitress, turning on any and all functionality to make sure that the request matches the RFC7230 standard. Certain proxy servers may not have this functionality though and users are encouraged to upgrade to the latest version of waitress instead. | ||||
| CVE-2022-24801 | 5 Debian, Fedoraproject, Oracle and 2 more | 6 Debian Linux, Fedora, Zfs Storage Appliance Kit and 3 more | 2025-04-23 | 8.1 High |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to version 22.4.0rc1, the Twisted Web HTTP 1.1 server, located in the `twisted.web.http` module, parsed several HTTP request constructs more leniently than permitted by RFC 7230. This non-conformant parsing can lead to desync if requests pass through multiple HTTP parsers, potentially resulting in HTTP request smuggling. Users who may be affected use Twisted Web's HTTP 1.1 server and/or proxy and also pass requests through a different HTTP server and/or proxy. The Twisted Web client is not affected. The HTTP 2.0 server uses a different parser, so it is not affected. The issue has been addressed in Twisted 22.4.0rc1. Two workarounds are available: Ensure any vulnerabilities in upstream proxies have been addressed, such as by upgrading them; or filter malformed requests by other means, such as configuration of an upstream proxy. | ||||
| CVE-2022-31117 | 3 Fedoraproject, Redhat, Ultrajson Project | 3 Fedora, Openstack, Ultrajson | 2025-04-23 | 5.9 Medium |
| UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. In versions prior to 5.4.0 an error occurring while reallocating a buffer for string decoding can cause the buffer to get freed twice. Due to how UltraJSON uses the internal decoder, this double free is impossible to trigger from Python. This issue has been resolved in version 5.4.0 and all users should upgrade to UltraJSON 5.4.0. There are no known workarounds for this issue. | ||||
| CVE-2022-21716 | 5 Debian, Fedoraproject, Oracle and 2 more | 6 Debian Linux, Fedora, Http Server and 3 more | 2025-04-22 | 7.5 High |
| Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 22.2.0, Twisted SSH client and server implement is able to accept an infinite amount of data for the peer's SSH version identifier. This ends up with a buffer using all the available memory. The attach is a simple as `nc -rv localhost 22 < /dev/zero`. A patch is available in version 22.2.0. There are currently no known workarounds. | ||||
| CVE-2022-31116 | 3 Fedoraproject, Redhat, Ultrajson Project | 3 Fedora, Openstack, Ultrajson | 2025-04-22 | 7.5 High |
| UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Affected versions were found to improperly decode certain characters. JSON strings that contain escaped surrogate characters not part of a proper surrogate pair were decoded incorrectly. Besides corrupting strings, this allowed for potential key confusion and value overwriting in dictionaries. All users parsing JSON from untrusted sources are vulnerable. From version 5.4.0, UltraJSON decodes lone surrogates in the same way as the standard library's `json` module does, preserving them in the parsed output. Users are advised to upgrade. There are no known workarounds for this issue. | ||||
| CVE-2021-22570 | 6 Debian, Fedoraproject, Google and 3 more | 11 Debian Linux, Fedora, Protobuf and 8 more | 2025-04-21 | 6.5 Medium |
| Nullptr dereference when a null char is present in a proto symbol. The symbol is parsed incorrectly, leading to an unchecked call into the proto file's name during generation of the resulting error message. Since the symbol is incorrectly parsed, the file is nullptr. We recommend upgrading to version 3.15.0 or greater. | ||||

| In Open vSwitch (OvS) 2.7.0, while parsing an OpenFlow role status message, there is a call to the abort() function for undefined role status reasons in the function `ofp_print_role_status_message` in `lib/ofp-print.c` that may be leveraged toward a remote DoS attack by a malicious switch. | ||||
| CVE-2017-9264 | 2 Openvswitch, Redhat | 3 Openvswitch, Enterprise Linux, Openstack | 2025-04-20 | N/A |
| In lib/conntrack.c in the firewall implementation in Open vSwitch (OvS) 2.6.1, there is a buffer over-read while parsing malformed TCP, UDP, and IPv6 packets in the functions `extract_l3_ipv6`, `extract_l4_tcp`, and `extract_l4_udp` that can be triggered remotely. | ||||
| CVE-2017-9265 | 2 Openvswitch, Redhat | 3 Openvswitch, Enterprise Linux, Openstack | 2025-04-20 | N/A |
| In Open vSwitch (OvS) v2.7.0, there is a buffer over-read while parsing the group mod OpenFlow message sent from the controller in `lib/ofp-util.c` in the function `ofputil_pull_ofp15_group_mod`. | ||||

| CVE-2017-11334 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 4.4 Medium |
| The address_space_write_continue function in exec.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (out-of-bounds access and guest instance crash) by leveraging use of qemu_map_ram_ptr to access guest ram block area. | ||||

| CVE-2017-14167 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Enterprise Linux and 1 more | 2025-04-20 | 8.8 High |
| Integer overflow in the load_multiboot function in hw/i386/multiboot.c in QEMU (aka Quick Emulator) allows local guest OS users to execute arbitrary code on the host via crafted multiboot header address values, which trigger an out-of-bounds write. | ||||
| CVE-2017-1000385 | 3 Debian, Erlang, Redhat | 4 Debian Linux, Erlang\/otp, Cloudforms Managementengine and 1 more | 2025-04-20 | N/A |
