[Bug 18612] New: AutoGK 2.55 crashes on close
http://bugs.winehq.org/show_bug.cgi?id=18612 Summary: AutoGK 2.55 crashes on close Product: Wine Version: 1.1.21 Platform: PC URL: http://www.autogk.me.uk/modules.php?name=Downloads OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: richedit AssignedTo: wine-bugs(a)winehq.org ReportedBy: dimesio(a)earthlink.net Created an attachment (id=21298) --> (http://bugs.winehq.org/attachment.cgi?id=21298) AutoGK crash +richedit trace Tested in 1.1.21 and 1.1.22 on openSUSE 11.1. AutoGK is a free, user-friendly front end for Avisynth and VirtualDubMod that automates the encoding process. It needs native msvfw32 and mfc42u to encode video in Wine, however, these overrides are not needed to start up the program and reproduce the crash, which only occurs on closing the program. To reproduce: Download and install AutoGK. (Installing in a virtual desktop works best.) Run it from the program directory. Close the program by clicking the close button in the upper right corner. AutoGK will crash, showing a dialog that says "Exception EAccessViolation in module AutoGK.exe at 00001F1B. Access violation at address 00401F1B in module 'AutoGK.exe'. Read of address 00000000." Using native riched20 solves the 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.

Unfortunately the richedit control implementation did a memcpy for the size of the buffer instead of the size of the text that is retrieved, causing a buffer overflow that leads to the crash in the application code. -- 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.

It also properly handles 0 values for the buffer or the buffer length in WM_GETTEXT or EM_GETTEXTEX. -- 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.
