Beskrivelse: mercenary har identificeret en sårbarhed i PHP, som kan udnyttes af ondsindede personer til at kompromittere et sårbart system. Sårbarheden skyldes en ikke-kontrolleret buffer i håndteringen af named pipe delen af "server" parameteren suppleret til "mysql_connect()" PHP funktionen i "HANDLE create_named_pipe()" funktionen i "libmysql.c". Dette kan udnyttes til at forårsage et stack-baseret buffer overflow via et PHP script der kalder "mysql_connect()" hvor "server" parameteren kan kontrolleres af en ondsindet person. NOTE: Exploit kode er offentliggjort. Sårbarheden er bekræftet i version 4.4.1 til Windows. Det rapporteres at version 4.3.10 og 4.4.0 til Windows også er sårbare. Andre versioner er muligvis også berørte. Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector. Løsning: Opdatér til version 4.4.3. http://www.php.net/downloads.php Rapporteret af / Kredit: mercenary Forløb: 03-08-2006: Opdaterede løsningen. 04-08-2006: Tilføjede CVE-reference.
