Description

An issue was discovered in MariaDB Server before 11.4.10, 11.5.x through 11.8.x before 11.8.6, and 12.x before 12.2.2. If the caching_sha2_password authentication plugin is installed, and some user accounts are configured to use it, a large packet can crash the server because sha256_crypt_r uses alloca.

Affected configurations

• mariadb mariadb (< 11.4.10) • mariadb mariadb (>= 11.5.0 < 11.8.6) • mariadb mariadb (>= 12.0.0 < 12.2.2)
