The remote host is affected by the vulnerability described in GLSA-200803-02 (Firebird: Multiple vulnerabilities)
Firebird does not properly handle certain types of XDR requests, resulting in an integer overflow (CVE-2008-0387). Furthermore, it is vulnerable to a buffer overflow when processing usernames (CVE-2008-0467).
Impact :
A remote attacker could send specially crafted XDR requests or an overly long username to the vulnerable server, possibly resulting in the remote execution of arbitrary code with the privileges of the user running the application.
Workaround :
There is no known workaround at this time.
