Perl DBI is a database access Application Programming Interface for the Perl language. perl-DBD-Pg allows Perl applications to access PostgreSQL database servers. A heap-based buffer overflow flaw was discovered in the pg_getline function implementation. If the pg_getline or getline functions read large, untrusted records from a database, it could cause an application using these functions to crash or, possibly, execute arbitrary code. Note: After installing this update, pg_getline may return more data than specified by its second argument, as this argument will be ignored. This is consistent with current upstream behavior. Previously, the length limit was not enforced, allowing a buffer overflow. A memory leak flaw was found in the function performing the de-quoting of BYTEA type values acquired from a database. An attacker able to cause an application using perl-DBD-Pg to perform a large number of SQL queries returning BYTEA records, could cause the application to use excessive amounts of memory or, possibly, crash. All users of perl-DBD-Pg are advised to upgrade to this updated package, which contains backported patches to fix these issues. Applications using perl-DBD-Pg must be restarted for the update to take effect.
