zeromq: stack-overflow on any server protected by encryption/authentication

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 on D-Link DIR-823G devices with firmware 1.02B03. There is a command injection in HNAP1 (exploitable with Authentication) via shell metacharacters in the IPAddress or Gateway field to SetStaticRouteSettings.

libssh2: integer overflow in kex_method_diffie_hellman_group_exchange_sha256_key_exchange in kex.c leads to out-of-bounds write

In libssh2 before 1.9.0, kex_method_diffie_hellman_group_exchange_sha256_key_exchange 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 _libssh2_check_length mistake, and is different from the various issues fixed in 1.8.1, such as CVE-2019-3855.

Pi-Hole 4.3 allows Command Injection.

Compal CH7465LG CH7465LG-NCIP-6.12.18.24-5p8-NOSH devices have Incorrect Access Control because of Improper Input Validation. The attacker can send a maliciously modified POST (HTTP) request containing shell commands, which will be executed on the device, to an backend API endpoint of the cable modem.

In Loopchain through 2.2.1.3, an attacker can escalate privileges from a low-privilege shell by changing the environment (aka injection in the DEFAULT_SCORE_HOST environment variable).

Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 have Improper Input Validation (issue 6 of 6).

Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 have Improper Input Validation (issue 4 of 6).

Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 have Improper Input Validation (issue 3 of 6).

Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 have Improper Input Validation (issue 2 of 6).

Citrix SD-WAN 10.2.x before 10.2.3 and NetScaler SD-WAN 10.0.x before 10.0.8 have Improper Input Validation (issue 1 of 6).

An issue was discovered in Mongoose before 6.15. The parse_mqtt() function in mg_mqtt.c has a critical heap-based buffer overflow.

apps/gsudo.c in gsudo in ToaruOS through 1.10.9 has a buffer overflow allowing local privilege escalation to the root user via the DISPLAY environment variable.

QEMU: guest agent guest_exec command execution

The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue

QEMU: QMP migrate command execution issue

The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue
