How LVS_SHAREIMAGELISTS is used? The cause here is a dereference to himl->magic (or whatever it's called), himl isn't null obviously, but is in freed memory block. (I'm not able to download it currently, it's to fat for my connection) -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

http://bugs.winehq.org/show_bug.cgi?id=20553 --- Comment #6 from Nikolay Sivov <bunglehead(a)gmail.com> 2009-11-13 21:37:17 --- So it looks like a problem here: --- if (!(infoPtr->dwStyle & LVS_SHAREIMAGELISTS)) { ImageList_Destroy(infoPtr->himlNormal); ImageList_Destroy(infoPtr->himlSmall); <- ImageList_Destroy(infoPtr->himlState); } --- Looking at chromium I see the following: --- void TableView::OnDestroy() { if (table_type_ == ICON_AND_TEXT) { HIMAGELIST image_list = ListView_GetImageList(GetNativeControlHWND(), LVSIL_SMALL); DCHECK(image_list); if (image_list) ImageList_Destroy(image_list); } } --- Such thing could certainly crash on Wine - you attach an imagelist to ListView without LVS_SHAREIMAGELISTS (at least I don't see it in cc file). After that you free imagelist and ListView tries to free it again on WM_NCDESTROY. Thing you should to test: - what ImageList_Destroy() does for obviously invalid pointer passed, maybe we just should protect it with some exception handler to check if a whole structure size is valid starting HIMAGELIST pointer. Actually I think it's a chromium bug (or not clean use) too. MSDN says: --- LVM_SETIMAGELIST --- The current image list will be destroyed when the list-view control is destroyed unless the LVS_SHAREIMAGELISTS style is set. If you use this message to replace one image list with another, your application must explicitly destroy all image lists other than the current one. --- -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Here was another problem discussed in this thread (corrupting heap overwriting area marked free), and it doesn't exist any more. Currently I see a possible fix for that using following condition: --- HeapSize(GetProcessHeap(), 0, himl) >= sizeof(void*) --- to determine if required field available to read. This will prevent from reading out of allocated area. Failure will be indicated by -1 return value. This check should be next after checking himl for null. P.S. I'm using sizeof(void*) here instead of sizeof(DWORD) cause of bug 20696 where I think it's possible to use vtable pointer as a magic (HIMAGELIST isn't reusable for another process anyway). -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

HeapSize is not a reliable way to test for a valid handle. If you want to check vtable or magic you can do that just as well without a HeapSize first. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Then it's a application bug here. I thought this invalid read caused by accessing first member (magic or vtable). If there's no way to do such check it's a chromium problem. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
