A vulnerability in Cisco WebEx Meetings Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. The vulnerability is due to insufficient limitations on the number of connections that can be made to the affected software. An attacker could exploit this vulnerability by opening multiple connections to the server and exhausting server resources. A successful exploit could cause the server to reload, resulting in a DoS condition. Cisco Bug IDs: CSCvf41006.

A vulnerability in the TCP state machine of Cisco RF Gateway 1 devices could allow an unauthenticated, remote attacker to prevent an affected device from delivering switched digital video (SDV) or video on demand (VoD) streams, resulting in a denial of service (DoS) condition. The vulnerability is due to a processing error with TCP connections to the affected device. An attacker could exploit this vulnerability by establishing a large number of TCP connections to an affected device and not actively closing those TCP connections. A successful exploit could allow the attacker to prevent the affected device from delivering SDV or VoD streams to set-top boxes. Cisco Bug IDs: CSCvf19887.

ImageMagick: Memory exhaustion in ReadPCXImage in coders/pcx.c

In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadPCXImage in coders/pcx.c, which allows attackers to cause a denial of service.

ImageMagick: Memory exhaustion in ReadSUNImage function in coders/sun.c

In ImageMagick 7.0.6-1, a memory exhaustion vulnerability was found in the function ReadSUNImage in coders/sun.c, which allows attackers to cause a denial of service.

ImageMagick: Memory leak in ReadMIFFImage function in coders/miff.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.

ImageMagick: Memory leak in ReadOnePNGImage function in coders/png.c

In ImageMagick before 6.9.9-4 and 7.x before 7.0.6-4, a crafted file could trigger a memory leak in ReadOnePNGImage in coders/png.c.

ImageMagick: Memory leak in the ReadMATImage function in coders/mat.c.

In ImageMagick before 6.9.8-5 and 7.x before 7.0.5-6, there is a memory leak in the ReadMATImage function in coders/mat.c.

tomcat: Handling of HTTP/2 GOAWAY frame for a connection did not close streams associated with that connection

In Apache Tomcat 9.0.0.M1 to 9.0.0.M18 and 8.5.0 to 8.5.12, the handling of an HTTP/2 GOAWAY frame for a connection did not close streams associated with that connection that were currently waiting for a WINDOW_UPDATE before allowing the application to write more data. These waiting streams each consumed a thread. A malicious client could therefore construct a series of HTTP/2 requests that would consume all available processing threads.

zookeeper: Incorrect input validation with wchp/wchc four letter words

Two four letter word commands "wchp/wchc" are CPU intensive and could cause spike of CPU utilization on Apache ZooKeeper server if abused, which leads to the server unable to serve legitimate client requests. Apache ZooKeeper thru version 3.4.9 and 3.5.2 suffer from this issue, fixed in 3.4.10, 3.5.3, and later.

Pre-authorization Start Remote Process vulnerabilities in Trend Micro OfficeScan 11.0 and XG may allow unauthenticated users who can access the OfficeScan server to start the fcgiOfcDDA.exe executable or cause a potential INI corruption, which may cause the server disk space to be consumed with dump files from continuous HTTP requests.

gedit: CPU consumption via crafted file

libgedit.a in GNOME gedit through 3.22.1 allows remote attackers to cause a denial of service (CPU consumption) via a file that begins with many '\0' characters.

ImageMagick: Excessive memory allocation in ReadWEBPImage function in coders/webp.c

ReadWEBPImage in coders/webp.c in ImageMagick 7.0.6-5 has an issue where memory allocation is excessive because it depends only on a length field in a header.

Scrapy 1.4 allows remote attackers to cause a denial of service (memory consumption) via large files because arbitrarily many files are read into memory, which is especially problematic if the files are then individually written in a separate thread to a slow storage resource, as demonstrated by interaction between dataReceived (in core/downloader/handlers/http11.py) and S3FilesStore.

Qemu: serial: host memory leakage 16550A UART emulation

Memory leak in the serial_exit_core function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.

Qemu: display: virtio-gpu: host memory leakage in virtio_gpu_resource_attach_backing

Memory leak in the virtio_gpu_resource_attach_backing function in hw/display/virtio-gpu.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (host memory consumption) via a large number of VIRTIO_GPU_CMD_RESOURCE_ATTACH_BACKING commands.

In libavformat/asfdec_f.c in FFmpeg 3.3.3, a DoS in asf_build_simple_index() due to lack of an EOF (End of File) check might cause huge CPU consumption. When a crafted ASF file, which claims a large "ict" field in the header but does not contain sufficient backing data, is provided, the for loop would consume huge CPU and memory resources, since there is no EOF check inside the loop.

exiv2: Stack consumption in the Exiv2::Internal::stringFormat function

There is a stack consumption vulnerability in the Exiv2::Internal::stringFormat function of image.cpp in Exiv2 0.26. A Crafted input will lead to a remote denial of service attack.

binutils: Infinite loop in the decode_line_info

decode_line_info in dwarf2.c in the Binary File Descriptor (BFD) library (aka libbfd), as distributed in GNU Binutils 2.29, allows remote attackers to cause a denial of service (infinite loop) via a crafted ELF file.
