Insight
Several buffer overflows have been discovered in PL/PgSQL as part of the PostgreSQL engine which could lead to the execution of arbitrary code. For the stable distribution (woody) these problems have been fixed in version 7.2.1-2woody8. For the unstable distribution (sid) these problems have been fixed in version 7.4.7-2. We recommend that you upgrade your postgresql packages.
