Buffer overflow in system firmware for EDK II may allow unauthenticated user to potentially enable escalation of privilege and/or denial of service via network access.
In PyYAML before 4.1, the yaml.load() API could execute arbitrary code. In other words, yaml.safeload is not used.
A buffer overflow in DOSBox 0.74-2 allows attackers to execute arbitrary code.
In ZeroMQ libzmq before 4.0.9, 4.1.x before 4.1.7, and 4.2.x before 4.3.2, a remote, unauthenticated client connecting to a libzmq application, running with a socket listening with CURVE encryption/authentication enabled, may cause a stack overflow and overwrite the stack with arbitrary data, due to a buffer overflow in the library. Users running public servers with the above configuration are highly encouraged to upgrade as soon as possible, as there are no known mitigations.
SchedMD Slurm 17.11.x, 18.08.0 through 18.08.7, and 19.05.0 allows SQL Injection.
An issue was discovered in Rsyslog v8.1908.0. contrib/pmcisconames/pmcisconames.c has a heap overflow in the parser for Cisco log messages. The parser tries to locate a log message delimiter (in this case, a space or a colon), but fails to account for strings that do not satisfy this constraint. If the string does not match, then the variable lenMsg will reach the value zero and will skip the sanity check that detects invalid log messages. The message will then be considered valid, and the parser will eat up the nonexistent colon delimiter. In doing so, it will decrement lenMsg, a signed integer, whose value was zero and now becomes minus one. The following step in the parser is to shift left the contents of the message. To do this, it will call memmove with the right pointers to the target and destination strings, but the lenMsg will now be interpreted as a huge value, causing a heap overflow.

IMAP and ManageSieve protocol parsers do not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes.
An issue was discovered in The Sleuth Kit (TSK) 4.6.6. There is an off-by-one overwrite due to an underflow on tools/hashtools/hfind.cpp while using a bogus hash table.

Cyrus IMAP 2.5.x before 2.5.14 and 3.x before 3.0.12 allows privilege escalation because an HTTP request may be interpreted in the authentication context of an unrelated previous request that arrived over the same connection.
Apache PDFBox 2.0.14 does not properly initialize the XML parser, which allows context-dependent attackers to conduct XML External Entity (XXE) attacks via a crafted XFDF.
Stack-based buffer overflow in the getkey function in parse.c in abcm2ps through 8.13.20 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
Stack-based buffer overflow in the delayedoutput function in music.c in abcm2ps through 8.13.20 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact.
Arbitrary command execution is possible in Git before 2.20.2, 2.21.x before 2.21.1, 2.22.x before 2.22.2, 2.23.x before 2.23.1, and 2.24.x before 2.24.1 because a "git submodule update" operation can run commands found in the .gitmodules file of a malicious repository.
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 MODBUSFCWRITEMULTIPLEREGISTERS 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 MODBUSFCWRITEMULTIPLECOILS case, aka VD-1302.
An issue was discovered in Singularity 3.1.0 to 3.2.0-rc2, a malicious user with local/network access to the host system (e.g. ssh) could exploit this vulnerability due to insecure permissions allowing a user to edit files within /run/singularity/instances/sing/<user>/<instance>. The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host.
A cross-site request forgery flaw was found in etcd 3.3.1 and earlier. An attacker can set up a website that tries to send a POST request to the etcd server and modify a key. Adding a key is done with PUT so it is theoretically safe (can't PUT from an HTML form or such) but POST allows creating in-order keys that an attacker can send.
A heap buffer overflow flaw was found in the SwiftShader component of the Chromium browser.

Use after free in WebBluetooth in Google Chrome prior to 78.0.3904.108 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted HTML page.
An issue was discovered in crun before 0.10.5. With a crafted image, it doesn't correctly check whether a target is a symlink, resulting in access to files outside of the container. This occurs in libcrun/linux.c and libcrun/chrootrealpath.c.
In libssh2 before 1.9.0, kexmethoddiffiehellmangroupexchangesha256keyexchange in kex.c has an integer overflow that could lead to an out-of-bounds read in the way packets are read from the server. A remote attacker who compromises a SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. This is related to an libssh2checklength mistake, and is different from the various issues fixed in 1.8.1, such as CVE-2019-3855.
etcd versions 3.2.x before 3.2.26 and 3.3.x before 3.3.11 are vulnerable to an improper authentication issue when role-based access control (RBAC) is used and client-cert-auth is enabled. If an etcd client server TLS certificate contains a Common Name (CN) which matches a valid RBAC username, a remote attacker may authenticate as that user with any valid (trusted) client certificate in a REST API request to the gRPC-gateway.
CServer::SendMsg in engine/server/server.cpp in Teeworlds 0.7.x before 0.7.5 allows remote attackers to shut down the server.
PDFResurrect 0.15 has a buffer overflow via a crafted PDF file because data associated with startxref and %%EOF is mishandled.
It was found that in ghostscript some privileged operators remained accessible from various places after the CVE-2019-6116 fix. A specially crafted PostScript file could use this flaw in order to, for example, have access to the file system outside of the constrains imposed by -dSAFER. Ghostscript versions before 9.27 are vulnerable.
An issue was discovered in AdvanceCOMP through 2.1. An invalid memory address occurs in the function advpngunfilter8 in lib/png.c. It can be triggered by sending a crafted file to a binary. It allows an attacker to cause a Denial of Service (Segmentation fault) or possibly have unspecified other impact when a victim opens a specially crafted file.
HTMLDOC 1.9.7 allows a stack-based buffer overflow in the hdstrlcpy() function in string.c (when called from rendercontents in ps-pdf.cxx) via a crafted HTML document.
