CVE-2012-1151: Medium severity Perl Perl vulnerability

Published Mar 9, 2012
·
Updated

Multiple format string vulnerabilities in dbdimp.c in DBD::Pg (aka DBD-Pg or libdbd-pg-perl) module before 2.19.0 for Perl allow remote PostgreSQL database servers to cause a denial of service (process crash) via format string specifiers in (1) a crafted database warning to the pgwarn function or (2) a crafted DBD statement to the dbdstprepare function.

Other sources

Two format string flaws were found in the way perl-DBD-Pg, a Perl language PostgreSQL DBI implementation, performed: 1) turning of database notices into appropriate Perl language warning messages, 2) preparation of particular DBD statement.

A rogue server could provide a specially-crafted database warning or specially-crafted DBD statement, which once processed by the perl-DBD-Pg interface would lead to perl-DBD-Pg based process crash.
