Date: May 23, 2004
Updated: May 22, 2006
Bug(s): #20837
ID: 200405-18

Synopsis


A buffer overflow via environmental variables in Firebird may allow a local
user to manipulate or destroy local databases and trojan the Firebird
binaries.


Background


Firebird is an open source relational database that runs on Linux,
Windows, and various UNIX systems.


Affected Packages

Package: dev-db/firebird
Vulnerable: < 1.5
Unaffected: >= 1.5
Architectures: All supported architectures


Description


A buffer overflow exists in three Firebird binaries (gds_inet_server,
gds_lock_mgr, and gds_drop) that is exploitable by setting a large
value to the INTERBASE environment variable.


Impact


An attacker could control program execution, allowing privilege
escalation to the UID of Firebird, full access to Firebird databases,
and trojaning the Firebird binaries. An attacker could use this to
compromise other user or root accounts.


Workaround


There is no known workaround.


Resolution


All users should upgrade to the latest version of Firebird:
