RedHat: Moderate: perl-DBD-Pg security update
Summary
Perl DBI is a database access Application Programming Interface (API) 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.
(CVE-2009-0663)
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
(the second argument) 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. (CVE-2009-1341)
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.
