MediaWiki 1.4.10 and 1.3.16 are security maintenance releases. A bug in edit submission handling could cause corruption of the previous revision in the database if an abnormal URL was used, such as those used by some spambots.
Affected releases: * 1.4.x <= 1.4.9; fixed in 1.4.10 * 1.3.x <= 1.3.15; fixed in 1.3.16
1.5 release candidates are not affected by this problem.
All publicly editable wikis are strongly recommended to upgrade immediately. 1.4 releases can be manually patched by changing this bit in EditPage.php:
~ function importFormData( &$request ) { ~ if( $request->wasPosted() ) {
to:
~ function importFormData( &$request ) { ~ if( $request->getVal( 'action' ) == 'submit' && ~ $request->wasPosted() ) {
1.3 releases can be manually patched by changing this bit in EditPage.php:
~ if( $this->tokenOk( $request ) ) { ~ $this->save = $request->wasPosted() && !$this->preview; ~ } else {
to:
~ if( $this->tokenOk( $request ) ) { ~ $this->save = $request->getVal( 'action' ) == 'submit' && ~ $request->wasPosted() && !$this->preview; ~ } else {
