When running Apache Tomcat versions 9.0.0.M1 to 9.0.0, 8.5.0 to 8.5.22, 8.0.0.RC1 to 8.0.46 and 7.0.0 to 7.0.81 with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default servlet to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

When using a VirtualDirContext with Apache Tomcat 7.0.0 to 7.0.80 it was possible to bypass security constraints and/or view the source code of JSPs for resources served by the VirtualDirContext using a specially crafted request.

When running Apache Tomcat 7.0.0 to 7.0.79 on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) it was possible to upload a JSP file to the server via a specially crafted request. This JSP could then be requested and any code it contained would be executed by the server.

When apr_time_exp*() or apr_os_exp_time*() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input.

In Apache Struts 2.0.0 through 2.3.33 and 2.5 through 2.5.10.1, using an unintentional expression in a Freemarker tag instead of string literals can lead to a RCE attack.

In Apache Kafka 0.10.0.0 to 0.10.2.1 and 0.11.0.0 to 0.11.0.1, authenticated Kafka clients may use impersonation via a manually crafted protocol message with SASL/PLAIN or SASL/SCRAM authentication when using the built-in PLAIN or SCRAM server implementations in Apache Kafka.

A vulnerability in Apache OpenOffice Writer DOC file parser before 4.1.4, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

A vulnerability in OpenOffice's PPT file parser before 4.1.4, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the function FillColorRow4 in utils.cpp when reading an image file by using cv::imread.

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the FillColorRow8 function in utils.cpp when reading an image file by using cv::imread.

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the FillUniColor function in utils.cpp when reading an image file by using cv::imread.

OpenCV (Open Source Computer Vision Library) through 3.3 has an invalid write in the cv::RLByteStream::getBytes function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by using cv::imread, as demonstrated by the 2-opencv-heapoverflow-fseek test case.

OpenCV (Open Source Computer Vision Library) through 3.3 has a denial of service (memory consumption) issue, as demonstrated by the 10-opencv-dos-memory-exhaust test case.

OpenCV (Open Source Computer Vision Library) through 3.3 has a buffer overflow in the cv::BmpDecoder::readData function in modules/imgcodecs/src/grfmt_bmp.cpp when reading an image file by using cv::imread, as demonstrated by the 4-buf-overflow-readData-memcpy test case.

OpenCV (Open Source Computer Vision Library) through 3.3 has a denial of service (CPU consumption) issue, as demonstrated by the 11-opencv-dos-cpu-exhaust test case.

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds read error in the function icvCvt_BGRA2BGR_8u_C4C3R when reading an image file by using cv::imread.

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds read error in the cv::RBaseStream::readBlock function in modules/imgcodecs/src/bitstrm.cpp when reading an image file by using cv::imread, as demonstrated by the 8-opencv-invalid-read-fread test case.

OpenCV (Open Source Computer Vision Library) through 3.3 has an out-of-bounds write error in the function FillColorRow1 in utils.cpp when reading an image file by using cv::imread.

In OpenEXR 2.2.0, a crafted image causes a heap-based buffer over-read in the hufDecode function in IlmImf/ImfHuf.cpp during exrmaketiled execution; it may result in denial of service or possibly unspecified other impact.

The tokenizer in QPDF 6.0.0 and 7.0.b1 is recursive for arrays and dictionaries, which allows remote attackers to cause a denial of service (stack consumption and segmentation fault) or possibly have unspecified other impact via a PDF document with a deep data structure, as demonstrated by a crash in QPDFObjectHandle::parseInternal in libqpdf/QPDFObjectHandle.cc.
