CVSS v3.1 |
| 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. |
| Synapse before 1.52.0 with URL preview functionality enabled will attempt to generate URL previews for media stream URLs without properly limiting connection time. Connections will only be terminated after `max_spider_size` (default: 10M) bytes have been downloaded, which can in some cases lead to long-lived connections towards the streaming media server (for instance, Icecast). This can cause excessive traffic and connections toward such servers if their stream URL is, for example, posted to a large room with many Synapse instances with URL preview enabled. Version 1.52.0 implements a timeout mechanism which will terminate URL preview connections after 30 seconds. Since generating URL previews for media streams is not supported and always fails, 1.53.0 additionally implements an allow list for content types for which Synapse will even attempt to generate a URL preview. Upgrade to 1.53.0 to fully resolve the issue. As a workaround, turn off URL preview functionality by setting `url_preview_enabled: false` in the Synapse configuration file. |
| Memory leak in the keyboard input event handlers support in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption) by rapidly generating large keyboard events. |
| In ImageMagick 7.0.6-3, a missing check for multidimensional data was found in coders/mat.c, leading to a memory leak in the function ReadImage in MagickCore/constitute.c, which allows attackers to cause a denial of service. |
| GraphicsMagick 1.3.26 has a memory leak vulnerability in the function CloneImage in magick/image.c. |
| In ImageMagick 7.0.6-8, a memory leak vulnerability was found in the function ReadMIFFImage in coders/miff.c, which allows attackers to cause a denial of service (memory consumption in NewLinkedList in MagickCore/linked-list.c) via a crafted file. |
| In ImageMagick 7.0.5-5, the ReadPCDImage function in pcd.c allows attackers to cause a denial of service (memory leak) via a crafted file. |
| ImageMagick 7.0.7-17 Q16 x86_64 has memory leaks in coders/msl.c, related to MSLPopImage and ProcessMSLScript, and associated with mishandling of MSLPushImage calls. |
| ImageMagick 7.0.6-6 has a memory leak in ReadMATImage in coders/mat.c. |
| Memory leak in the virtio_gpu_object_create function in drivers/gpu/drm/virtio/virtgpu_object.c in the Linux kernel through 4.11.8 allows attackers to cause a denial of service (memory consumption) by triggering object-initialization failures. |
| In lib/ofp-util.c in Open vSwitch (OvS) before 2.8.1, there are multiple memory leaks while parsing malformed OpenFlow group mod messages. NOTE: the vendor disputes the relevance of this report, stating "it can only be triggered by an OpenFlow controller, but OpenFlow controllers have much more direct and powerful ways to force Open vSwitch to allocate memory, such as by inserting flows into the flow table." |
| Memory leak in the virtio_gpu_set_scanout function in hw/display/virtio-gpu.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (memory consumption) via a large number of "VIRTIO_GPU_CMD_SET_SCANOUT:" commands. |
| A vulnerability in the implementation of Common Industrial Protocol (CIP) functionality in Cisco Industrial Ethernet 2000 Series Switches could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to a system memory leak. More Information: CSCvc54788. Known Affected Releases: 15.2(5.4.32i)E2. Known Fixed Releases: 15.2(5.4.62i)E2. |
| In LibTIFF 4.0.8, there is a memory leak in tif_jbig.c. A crafted TIFF document can lead to a memory leak resulting in a remote denial of service attack. |
| GraphicsMagick 1.3.26 has a Memory Leak in the PersistCache function in magick/pixel_cache.c during writing of Magick Persistent Cache (MPC) files. |
| In ImageMagick 7.0.5-5, the ReadBMPImage function in bmp.c allows attackers to cause a denial of service (memory leak) via a crafted file. |
| In ImageMagick 7.0.5-5, the ReadJNGImage function in png.c allows attackers to cause a denial of service (memory leak) via a crafted file. |
| In ImageMagick 7.0.5-5, the ReadSFWImage function in sfw.c allows attackers to cause a denial of service (memory leak) via a crafted file. |
| In ImageMagick 7.0.5-5, the ReadEXRImage function in exr.c allows attackers to cause a denial of service (memory leak) via a crafted file. |
| In ImageMagick 7.0.5-5, the ReadDCMImage function in dcm.c allows attackers to cause a denial of service (memory leak) via a crafted file. |
