An issue was discovered in the MQTT server in Contiki-NG before 4.2. The function parse_publish_vhdr() that parses MQTT PUBLISH messages with a variable length header uses memcpy to input data into a fixed size buffer. The allocated buffer can fit only MQTT_MAX_TOPIC_LENGTH (default 64) bytes, and a length check is missing. This could lead to Remote Code Execution via a stack-smashing attack (overwriting the function return address). Contiki-NG does not separate the MQTT server from other servers and the OS modules, so access to all memory regions is possible.

php: Serializing or unserializing COM objects crashes

ext/standard/var_unserializer.c in PHP 5.x through 7.1.24 allows attackers to cause a denial of service (application crash) via an unserialize call for the com, dotnet, or variant class.

Buffer overflow in DNS SRV and NAPTR lookups in Digium Asterisk 15.x before 15.6.2 and 16.x before 16.0.1 allows remote attackers to crash Asterisk via a specially crafted DNS SRV or NAPTR response, because a buffer size is supposed to match an expanded length but actually matches a compressed length.

The BluStar component in Mitel InAttend before 2.5 SP3 and CMG before 8.4 SP3 Suite Servers has a default password, which could allow remote attackers to gain unauthorized access and execute arbitrary scripts with potential impacts to the confidentiality, integrity and availability of the system.

Buffer overflow in apply.cgi on TRENDnet TEW-632BRP 1.010B32 and TEW-673GRU devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (with authentication).

Buffer overflow in video.cgi on TRENDnet TV-IP110WN V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (without authentication).

Buffer overflow in network.cgi on TRENDnet TV-IP110WN V1.2.2 build 68, V1.2.2.65, and V1.2.2 build 64 and TV-IP121WN V1.2.2 build 28 devices allows attackers to hijack the control flow to any attacker-specified location by crafting a POST request payload (without authentication).

In LibSass 3.5-stable, there is an illegal address access at Sass::Eval::operator that will lead to a DoS attack.

ncurses: Null pointer dereference at function _nc_name_match

In ncurses, possibly a 6.x version, there is a NULL pointer dereference at the function _nc_name_match that will lead to a denial of service attack. NOTE: the original report stated version 6.1, but the issue did not reproduce for that version according to the maintainer or a reliable third-party

ncurses: Null pointer dereference at function _nc_parse_entry in parse_entry.c

In ncurses 6.1, there is a NULL pointer dereference at function _nc_parse_entry in parse_entry.c that will lead to a denial of service attack. The product proceeds to the dereference code path even after a "dubious character `*' in name or alias field" detection.

ethereumjs-vm 2.4.0 allows attackers to cause a denial of service (vm.runCode failure and REVERT) via a "code: Buffer.from(my_code, 'hex')" attribute. NOTE: the vendor disputes this because REVERT is a normal bytecode that can be triggered from high-level source code, leading to a normal programmatic execution result.

Memory corruption in PDMODELProvidePDModelHFT in pdmodel.dll in pdfforge PDF Architect 6 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact because of a "Data from Faulting Address controls Code Flow" issue.

In Libav 12.3, there is an invalid memory access in vc1_decode_frame in libavcodec/vc1dec.c that allows attackers to cause a denial-of-service via a crafted aac file. NOTE: This may be a duplicate of CVE-2017-17127

An issue was discovered in several Bosch IP cameras for firmware versions 6.32 and higher. A malicious client could potentially succeed in the unauthorized execution of code on the device via the network interface.

FFmpeg before commit 2b46ebdbff1d8dec7a3d8ea280a612b91a582869 contains a Buffer Overflow vulnerability in asf_o format demuxer that can result in heap-buffer-overflow that may result in remote code execution. This attack appears to be exploitable via specially crafted ASF file that has to be provided as input to FFmpeg. This vulnerability appears to have been fixed in 2b46ebdbff1d8dec7a3d8ea280a612b91a582869 and later.

VT-Designer Version 2.1.7.31 is vulnerable by the program reading the contents of a file (which is already in memory) into another heap-based buffer, which may cause the program to crash or allow remote code execution.

An issue was discovered on Epson WorkForce WF-2861 10.48 LQ22I3, 10.51.LQ20I6 and 10.52.LQ17IA devices. On the 'Air Print Setting' web page, if the data for 'Bonjour Service Location' at /PRESENTATION/BONJOUR is more than 251 bytes when sending data for Air Print Setting, then the device no longer functions until a reboot.

The ProcessMimeEntity function in util-decode-mime.c in Suricata 4.x before 4.0.6 allows remote attackers to cause a denial of service (segfault and daemon crash) via crafted input to the SMTP parser, as exploited in the wild in November 2018.

Artha ~ The Open Thesaurus 1.0.3.0 has a Buffer Overflow.

Py-EVM v0.2.0-alpha.33 allows attackers to make a vm.execute_bytecode call that triggers computation._stack.values with '"stack": [100, 100, 0]' where b'\x' was expected, resulting in an execution failure because of an invalid opcode. This is reportedly related to "smart contracts can be executed indefinitely without gas being paid."
