Insufficient control flow management in BIOS firmware for 8th, 9th, 10th Generation Intel(R) Core(TM), Intel(R) Celeron(R) Processor 4000 & 5000 Series Processors may allow an authenticated user to potentially enable denial of service via adjacent access.

dnsmasq: Improper bounds checking leads to a buffer overread

Improper bounds checking in Dnsmasq before 2.76 allows an attacker controlled DNS server to send large DNS packets that result in a read operation beyond the buffer allocated for the packet, a different vulnerability than CVE-2017-14491.

ModuleEditor::convertInstrument in tracker/ModuleEditor.cpp in MilkyTracker 1.02.00 has a heap-based buffer overflow.

LoaderXM::load in LoaderXM.cpp in milkyplay in MilkyTracker 1.02.00 has a stack-based buffer overflow.

poppler: divide-by-zero in function SplashOutputDev::tilingPatternFill in SplashOutputDev.cc

An issue was discovered in Poppler through 0.78.0. There is a divide-by-zero error in the function SplashOutputDev::tilingPatternFill at SplashOutputDev.cc.

opencv: NULL pointer dereference in function cv::XMLParser::parse() in persistence_xml.cpp leading to DoS

An issue was discovered in OpenCV before 4.1.1. There is a NULL pointer dereference in the function cv::XMLParser::parse at modules/core/src/persistence.cpp.

The GOsa_Filter_Settings cookie in GONICUS GOsa 2.7.5.2 is vulnerable to PHP objection injection, which allows a remote authenticated attacker to perform file deletions (in the context of the user account that runs the web server) via a crafted cookie value, because unserialize is used to restore filter settings from a cookie.

XMFile::read in XMFile.cpp in milkyplay in MilkyTracker 1.02.00 has a heap-based buffer overflow.

An issue was discovered in libmodbus before 3.0.7 and 3.1.x before 3.1.5. There is an out-of-bounds read for the MODBUS_FC_WRITE_MULTIPLE_REGISTERS case, aka VD-1301.

An issue was discovered in libmodbus before 3.0.7 and 3.1.x before 3.1.5. There is an out-of-bounds read for the MODBUS_FC_WRITE_MULTIPLE_COILS case, aka VD-1302.

nfdump 1.6.17 and earlier is affected by an integer overflow in the function Process_ipfix_template_withdraw in ipfix.c that can be abused in order to crash the process remotely (denial of service).

An issue was discovered in Libav 12.3. Division by zero in range_decode_culshift in libavcodec/apedec.c allows remote attackers to cause a denial of service (application crash), as demonstrated by avconv.

In mpc8_read_header in libavformat/mpc8.c in Libav 12.3, an input file can result in an avio_seek infinite loop and hang, with 100% CPU consumption. Attackers could leverage this vulnerability to cause a denial of service via a crafted file.

openstack-nova: Nova server resource faults leak external exception details

An issue was discovered in OpenStack Nova before 17.0.12, 18.x before 18.2.2, and 19.x before 19.0.2. If an API request from an authenticated user ends in a fault condition due to an external exception, details of the underlying environment may be leaked in the response, and could include sensitive configuration or other data.

libopenmpt before 0.4.5 allows a crash during playback due to an out-of-bounds read in XM and MT2 files.

In Libav 12.3, there is an infinite loop in the function wv_read_block_header() in the file wvdec.c.

exiv2: Out-of-bounds read in Exiv2::MrwImage::readMetadata() in mrwimage.cpp

In Exiv2 0.27.99.0, there is an out-of-bounds read in Exiv2::MrwImage::readMetadata() in mrwimage.cpp. It could result in denial of service.
