PAM-MySQL contains a double-free vulnerability that may allow a remote attacker to execute arbitrary code or cause a denial-of-service condition.
PAM-MySQL provides a Pluggable Authentication Module (PAM) interface to a MySQL database. PAM-MySQL does not securely handle a pointer returned by the pam_get_item() routine, which results in a double-free vulnerability. The vulnerability exists if the following conditions are present:
If a remote attacker supplies a specially crafted password to a vulnerable PAM-MySQL installation, that attacker may be able to crash the PAM-MySQL process. Note that it may be possible to exploit this vulnerability to execute arbitrary code.
