Mandriva: Updated libwmf packages fix vulnerability Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Mandrake A flaw in libgd2 was found by Xavier Roche where it would not correctly validate PNG callback results. If an application linked against libgd2 was tricked into processing a specially-crafted PNG file, it could cause a denial of service scenario via CPU resource consumption. Libwmf uses an embedded copy of the gd source and may also be affected by this issue. The updated packages have been patched to prevent this issue.
