The remote host is missing an update to libdbd-pg-perl announced via advisory DSA 1780-1.

Two vulnerabilities have been discovered in libdbd-pg-perl, the DBI driver module for PostgreSQL database access (DBD::Pg). CVE-2009-0663 A heap-based buffer overflow may allow attackers to execute arbitrary code through applications which read rows from the database using the pg_getline and getline functions. (More common retrieval methods, such as selectall_arrayref and fetchrow_array, are not affected.) CVE-2009-1341 A memory leak in the routine which unquotes BYTEA values returned from the database allows attackers to cause a denial of service. For the old stable distribution (etch), these problems have been fixed in version 1.49-2+etch1. For the stable distribution (lenny) and the unstable distribution (sid), these problems have been fixed in version 2.1.3-1 before the release of lenny. We recommend that you upgrade your libdbd-pg-perl package.
