MariaDB: Pre-authentication `size_t` integer underflow → out-of-bounds read / server crash in MariaDB `caching_sha2_password` (auth_mysql_sha2) via an RSA-OAEP

A pre-authentication integer underflow vulnerability was discovered in the cachingsha2password authentication plugin. When a client sent an RSA-OAEP encrypted empty message over plaintext TCP, the decrypted length was not validated before being used in a subtraction operation. This caused a sizet...

MariaDB: Stack Buffer Overflow via Crafted keyseg->start/ keyseg->length in .MYI File (MariaDB MyISAM)

A stack buffer overflow vulnerability was discovered in the MyISAM storage engine of MariaDB. The vulnerability was caused by lack of validation of the "keyseg-start" and "keyseg-length" fields read from the .MYI file. This allowed an attacker to write data beyond the bounds of a fixed-size stack...

MariaDB: Heap Memory Disclosure via Integer Underflow in Item_func_json_arrayagg::cut_max_length in MariaDB Server

A vulnerability was discovered in the JSONARRAYAGG aggregate function of MariaDB Server. The vulnerability was caused by an integer underflow in the cutmaxlength function, which could allow an authenticated user to read arbitrary heap memory from the server process. The vulnerability was introduc...
