Synopsis:	Moderate: perl-DBD-Pg security update
Issue date:	2009-05-13
CVE Names:	CVE-2009-0663 CVE-2009-1341

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)

Applications using perl-DBD-Pg must be restarted for the update to take
effect.
