Perl DBD-Pg Module: Arbitrary code execution

Background

DBD-Pg is a PostgreSQL interface module for Perl.

Description

Format string vulnerabilities have been found in the the “pg_warn()” and “dbd_st_prepare()” functions in dbdimp.c.

Impact

A remote PostgreSQL server could send specially crafted database warnings or DBD statements, possibly resulting in execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All users of the Perl DBD-Pg module should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=dev-perl/DBD-Pg-2.19.0"
