Description

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.
