Safari 4.0.5

Safari 4.0.5 is voornamelijk een beveiligingsupdate voor Apples browser. Zo worden maar liefst zestien lekken in Safari 4.0.5 dichtgeplakt. Verder zijn de stabiliteit van enkele plugins en de weergave van websites met SVG vergroot en zijn de prestaties van Top Sites verbeterd. Ook is een probleem opgelost waardoor Safari veranderingen in de instellingen van Linksys-routers blokkeerde.

De opgeloste beveiligingslekken worden door Secunia als kritiek beoordeeld. Negen zitten in de onderliggende Webkit-engine die Apple gebruikt als motor voor Safari. Vier in de verwerking van afbeeldingen door Apples browser. Zes van de zestien lekken hebben trouwens alleen betrekking op de Windows-versie van Safari. De overige tien spelen zowel onder Windows als Mac OS X op.

Release notes:

• Performance improvements for Top Sites
• Stability improvements for 3rd-party plug-ins
• Stability improvements for websites with online forms and Scalable Vector Graphics
• Fixes an issue that prevented Safari from changing settings on some Linksys routers

Opgeloste beveiligingslekken:
