Firebird server hangs when using specific clumplet on batch creation
Résumé
Firebird server hangs when using specific clumplet on batch creation
Description d'origine
La description telle que publiée par la source (souvent en anglais).
Firebird is an open-source relational database management system. In versions prior to 5.0.4, 4.0.7 and 3.0.14, the ClumpletReader::getClumpletSize() function can overflow the totalLength value when parsing a Wide type clumplet, causing an infinite loop. An authenticated user with INSERT privileges on any table can exploit this via a crafted Batch Parameter Block to cause a denial of service against the server. This issue has been fixed in versions 5.0.4, 4.0.7 and 3.0.14.
