In all versions of libyang before 1.0-r5, a stack-based buffer overflow was discovered in the way libyang parses YANG files with a leaf of type "identityref". An application that uses libyang to parse untrusted YANG files may be vulnerable to this flaw, which would allow an attacker to cause a denial of service or possibly gain code execution.

scm/define-stencil-commands.scm in LilyPond through 2.20.0, and 2.21.x through 2.21.4, when -dsafe is used, lacks restrictions on embedded-ps and embedded-svg, as demonstrated by including dangerous PostScript 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.

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.

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.

Multiple integer overflows exist in MATIO before 1.5.16, related to mat.c, mat4.c, mat5.c, mat73.c, and matvarstruct.c

WordPress before 5.5.2 allows attackers to gain privileges via XML-RPC.

wp-includes/class-wp-xmlrpc-server.php in WordPress before 5.5.2 allows attackers to gain privileges by using XML-RPC to comment on a post.

isbloginstalled in wp-includes/functions.php in WordPress before 5.5.2 improperly determines whether WordPress is already installed, which might allow an attacker to perform a new installation, leading to remote code execution (as well as a denial of service for the old installation).

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.

DISPUTED systemd 239 through 245 accepts any certificate signed by a trusted certificate authority for DNS Over TLS. Server Name Indication (SNI) is not sent, and there is no hostname validation with the GnuTLS backend. NOTE: This has been disputed by the developer as not a vulnerability since hostname validation does not have anything to do with this issue (i.e. there is no hostname to be sent).

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.
