| 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. |
| In ImageMagick 7.0.7-12 Q16, a memory leak vulnerability was found in the function ReadMATImage in coders/mat.c, which allows attackers to cause a denial of service via a crafted MAT image file. |
| The ReadTGAImage function in coders\tga.c in ImageMagick 7.0.5-6 has a memory leak vulnerability that can cause memory exhaustion via invalid colors data in the header of a TGA or VST file. |
| The ReadMATImage function in coders/mat.c in ImageMagick through 6.9.9-3 and 7.x through 7.0.6-3 has memory leaks involving the quantum_info and clone_info data structures. |
| The WritePICONImage function in coders/xpm.c in ImageMagick 7.0.6-4 allows remote attackers to cause a denial of service (memory leak) via a crafted file. |
| The ReadMAGICKImage function in coders/magick.c in ImageMagick 7.0.6-4 allows remote attackers to cause a denial of service (memory leak) via a crafted file. |
| The WritePICONImage function in coders/xpm.c in ImageMagick 7.0.6-4 allows remote attackers to cause a denial of service (memory leak) via a crafted file that is mishandled in an OpenPixelCache call. |
| The WritePICONImage function in coders/xpm.c in ImageMagick 7.0.6-4 allows remote attackers to cause a denial of service (memory leak) via a crafted file that is mishandled in an AcquireSemaphoreInfo call. |
| A vulnerability in the Simple Network Management Protocol (SNMP) subsystem of Cisco Wireless LAN Controllers could allow an authenticated, remote attacker to cause an affected device to restart, resulting in a denial of service (DoS) condition. The vulnerability is due to a memory leak that occurs on an affected device after the device fails to deallocate a buffer that is used when certain MIBs are polled. An attacker who knows the SNMP Version 2 SNMP Read string or has valid SNMP Version 3 credentials for an affected device could repeatedly poll the affected MIB object IDs (OIDs) and consume available memory on the device. When memory is sufficiently depleted on the device, the device will restart, resulting in a DoS condition. Cisco Bug IDs: CSCvc71674. |
| ImageMagick 7.0.6-5 has memory leaks in the parse8BIMW and format8BIM functions in coders/meta.c, related to the WriteImage function in MagickCore/constitute.c. |
| The ProcessMSLScript function in coders/msl.c in ImageMagick before 6.9.9-5 and 7.x before 7.0.6-5 allows remote attackers to cause a denial of service (memory leak) via a crafted file, related to the WriteMSLImage function. |
| In ImageMagick 7.0.6-1, a memory leak vulnerability was found in the function ReadWMFImage in coders/wmf.c, which allows attackers to cause a denial of service in CloneDrawInfo in draw.c. |
| In ImageMagick 7.0.6-1, a memory leak vulnerability was found in the function ReadPESImage in coders/pes.c, which allows attackers to cause a denial of service, related to ResizeMagickMemory in memory.c. |
| In ImageMagick 7.0.6-6, a memory leak vulnerability was found in the function WritePCXImage in coders/pcx.c, which allows attackers to cause a denial of service via a crafted file. |
| In ImageMagick 7.0.6-6, a memory leak vulnerability was found in the function WriteOneJNGImage in coders/png.c, which allows attackers to cause a denial of service (WriteJNGImage memory consumption) via a crafted file. |
| In ImageMagick 7.0.6-5, a memory leak vulnerability was found in the function ReadMATImage in coders/mat.c, which allows attackers to cause a denial of service via a crafted file. |
