CVE-2022-38060 2 Openstack, Redhat 2 Kolla, Openstack 2025-05-07 8.8 High
A privilege escalation vulnerability exists in the sudo functionality of OpenStack Kolla git master 05194e7618. A misconfiguration in /etc/sudoers within a container can lead to increased privileges.
CVE-2022-41723 2 Golang, Redhat 22 Go, Hpack, Http2 and 19 more 2025-05-05 7.5 High
A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of small requests.
CVE-2025-43859 1 Redhat 2 Ansible Automation Platform, Openstack 2025-04-29 9.1 Critical
h11 is a Python implementation of HTTP/1.1. Prior to version 0.16.0, a leniency in h11's parsing of line terminators in chunked-coding message bodies can lead to request smuggling vulnerabilities under certain conditions. This issue has been patched in version 0.16.0. Since exploitation requires the combination of buggy h11 with a buggy (reverse) proxy, fixing either component is sufficient to mitigate this issue.
CVE-2020-35498 4 Debian, Fedoraproject, Openvswitch and 1 more 5 Debian Linux, Fedora, Openvswitch and 2 more 2025-04-23 7.5 High
A vulnerability was found in openvswitch. A limitation in the implementation of userspace packet parsing can allow a malicious user to send a specially crafted packet causing the resulting megaflow in the kernel to be too wide, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2022-21712 4 Debian, Fedoraproject, Redhat and 1 more 4 Debian Linux, Fedora, Openstack and 1 more 2025-04-23 7.5 High
twisted is an event-driven networking engine written in Python. In affected versions twisted exposes cookies and authorization headers when following cross-origin redirects. This issue is present in the `twited.web.RedirectAgent` and `twisted.web. BrowserLikeRedirectAgent` functions. Users are advised to upgrade. There are no known workarounds.
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.
CVE-2017-7400 2 Openstack, Redhat 2 Horizon, Openstack 2025-04-20 N/A
OpenStack Horizon 9.x through 9.1.1, 10.x through 10.0.2, and 11.0.0 allows remote authenticated administrators to conduct XSS attacks via a crafted federation mapping.
CVE-2017-6414 2 Libcacard Project, Redhat 2 Libcacard, Openstack 2025-04-20 6.5 Medium
Memory leak in the vcard_apdu_new function in card_7816.c in libcacard before 2.5.3 allows local guest OS users to cause a denial of service (host memory consumption) via vectors related to allocating a new APDU object.
CVE-2017-7549 2 Openstack, Redhat 3 Instack-undercloud, Openstack, Openstack-director 2025-04-20 N/A
A flaw was found in instack-undercloud 7.2.0 as packaged in Red Hat OpenStack Platform Pike, 6.1.0 as packaged in Red Hat OpenStack Platform Oacta, 5.3.0 as packaged in Red Hat OpenStack Newton, where pre-install and security policy scripts used insecure temporary files. A local user could exploit this flaw to conduct a symbolic-link attack, allowing them to overwrite the contents of arbitrary files.
CVE-2017-16239 2 Openstack, Redhat 2 Nova, Openstack 2025-04-20 N/A
In OpenStack Nova through 14.0.9, 15.x through 15.0.7, and 16.x through 16.0.2, by rebuilding an instance, an authenticated user may be able to circumvent the Filter Scheduler bypassing imposed filters (for example, the ImagePropertiesFilter or the IsolatedHostsFilter). All setups using Nova Filter Scheduler are affected. Because of the regression described in Launchpad Bug #1732947, the preferred fix is a 14.x version after 14.0.10, a 15.x version after 15.0.8, or a 16.x version after 16.0.3.
CVE-2017-15268 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-20 N/A
Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c.
CVE-2017-5973 3 Debian, Qemu, Redhat 5 Debian Linux, Qemu, Enterprise Linux and 2 more 2025-04-20 5.5 Medium
The xhci_kick_epctx function in hw/usb/hcd-xhci.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (infinite loop and QEMU process crash) via vectors related to control transfer descriptor sequence.
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-2014-0145 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2025-04-20 N/A
Multiple buffer overflows in QEMU before 1.7.2 and 2.x before 2.0.0, allow local users to cause a denial of service (crash) or possibly execute arbitrary code via a large (1) L1 table in the qcow2_snapshot_load_tmp in the QCOW 2 block driver (block/qcow2-snapshot.c) or (2) uncompressed chunk, (3) chunk length, or (4) number of sectors in the DMG block driver (block/dmg.c).
