In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types.

In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types.

Affected: openEuler:22.03-LTS: mosquitto

Mosquitto is an open source message broker that implements the MQ Telemetry Transport protocol version 3.1 and 3.1.1 MQTT provides a lightweight method of carrying out messaging using a publish/subscribe model. This makes it suitable for "machine to machine" messaging such as with low power sensors or mobile devices such as phones, embedded computers or micro-controllers like the Arduino. Security Fix(es): In Mosquitto before 2.0.16, a memory leak occurs when clients send v5 CONNECT packets with a will message that contains invalid property types. (CVE-2023-3592) In Eclipse Mosquito before and including 2.0.5, establishing a connection to the mosquitto server without sending data causes the EPOLLOUT event to be added, which results excessive CPU consumption. This could be used by a malicious actor to perform denial of service type attack. This issue is fixed in 2.0.6

(CVE-2023-5632)

The multiScan and picoScan are vulnerable to a denial-of-service (DoS) attack. A remote attacker can exploit this vulnerability by conducting a Slowloris-type attack, causing the web page to become unresponsive. Tencent RapidJSON is vulnerable to privilege escalation due to an integer underflow in the `GenericReader::ParseNumber()` function of `include/rapidjson/reader.h` when parsing JSON text from a stream. An attacker needs to send the victim a crafted file which needs to be opened; this triggers the integer underflow vulnerability (when the file is parsed), leading to elevation of privilege.

An attacker needs to send the victim a crafted file which needs to be opened; this triggers the integer overflow vulnerability (when the file is parsed), leading to elevation of privilege. SQLite through 3.40.0, when relying on --safe for execution of an untrusted CLI script, does not properly implement the azProhibitedFunctions protection mechanism, and instead allows UDF functions such as WRITEFILE. A segmentation fault can occur in the sqlite3.exe command-line component of SQLite 3.36.0 via the idxGetTableInfo function when there is a crafted SQL query. NOTE: the vendor disputes the relevance of this report because a sqlite3.exe user already has full privileges (e.g., is intentionally all…
