[Bug 49747] New: ICO_ExtractIconExW causes crash on incomplete windows executable
https://bugs.winehq.org/show_bug.cgi?id=49747 Bug ID: 49747 Summary: ICO_ExtractIconExW causes crash on incomplete windows executable Product: Wine Version: 5.0 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: user32 Assignee: wine-bugs(a)winehq.org Reporter: andi(a)notmuch.email Distribution: --- Created attachment 68049 --> https://bugs.winehq.org/attachment.cgi?id=68049 backtrace of explorer.exe crashing I have 31% of a binary in a local directory because some installer/patcher crashed during installation. Whenever I use `winefile` or `wine explorer.exe` and scroll to that file in the directory wine crashes with the attached backtrace. It appears to be related to the ICO handling code within wine that expects more input but that doesn't exist yet. Attached is the backtrace of running the patcher for the "Dark Age of Camelot" freeshard "Phoenix" (https://playphoenix.online) which did cause this issue for me. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=49747 --- Comment #5 from KRosUser <kyle.kcsoftwares@gmail.com> --- To reproduce the issue, take any exe file: Find .rsrc offset using "objdump -h target.exe" Truncate the file while only including just first 500 bytes of .rsrc, e.g. if offset was 0x00027e00, run `dd if=./target.exe of=./broken.exe bs=1 count=$((0x0002800)) -- Do not reply to this email, post in Bugzilla using the above URL to reply.
