CVE-2005-0247

CVE-2005-0247 describes multiple buffer overflow vulnerabilities in PostgreSQL versions 8.0.1 and earlier, specifically within the gram.y file. These flaws could allow authenticated attackers to execute arbitrary code by crafting SQL statements with an excessive number of variables, impacting functions like read_sql_construct, make_select_stmt, and make_fetch_stmt. With a CVSS score of 6.5, this vulnerability is of medium severity, requiring authentication (Au:S) but having low attack complexity (AC:L), and could lead to partial compromise of confidentiality, integrity, and availability (C:P/I:P/A:P). There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage, indicating it is not a widely exploited or discussed threat.
