[Bug 60241] New: Claude Core review report(a lot of copy paste and logic bugs uncovered)

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=60241 Bug ID: 60241 Summary: Claude Core review report(a lot of copy paste and logic bugs uncovered) Product: Wine Version: 11.15 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: mikrutrafal(a)protonmail.com Target Milestone: --- Distribution: --- Created attachment 81942 --> http://bugs.winehq.org/attachment.cgi?id=81942 Html report, with ~1900 possible bugs in various modules Over the past month, whenever I had some free tokens available, I used Claude Code to review the Wine(and also other open source projects) codebase step by step I have attached an HTML file containing the graphical report, which contains info about ~1900 problematic places(copy-paste bugs, use-after-free, logic problems, etc.). I know that reporting multiple problems in a single bug report is usually not encouraged, but otherwise I would have flooded the entire Bugzilla tracker. Html report can also be found here: https://github.com/qarmin/ClaudeReports/blob/master/wine_20260823.html I have created reports using the same html template for many other open-source projects, like Box64, FEX, image-rs, lofty, Strawberry, and many others. These projects have already fixed bugs that were found through these reports(there were also some false positives). The report contains direct links to the Wine GitLab repository, the exact commit on which the report was created, a description of each bug, and a possible fix. I can regenerate the report if needed. Here are some examples of bugs that I'm sure are actual bugs: //////////////////////////////////////////////////// ### CPY_3 `HIGH` **Description:** In `ImmGetImeMenuItemsA` and `ImmGetImeMenuItemsW`, the per-item conversion loop copies from a fixed index `1` instead of the loop variable `i`: `memcpy( &menuA[i], &menuW[1], sizeof(IMEMENUITEMINFOA) )` and, symmetrically, `memcpy( &menuW[i], &menuA[1], sizeof(IMEMENUITEMINFOA) )`. Every output element ends up filled with data copied from source index `1` (wrong data for all `i != 1`), and when `ret` is `1` this also reads `menuW[1]`/`menuA[1]`, one element past what was populated/allocated for a single-item result - an out-of-bounds read. **Locations:** ```c memcpy( &menuA[i], &menuW[1], sizeof(IMEMENUITEMINFOA) ); ``` **Fix:** Use the loop index instead of the literal `1` in both functions: ```c memcpy( &menuA[i], &menuW[i], sizeof(IMEMENUITEMINFOA) ); ``` //////////////////////////////////////////////////// ### LOGIC_66 `MEDIUM` **Description:** In `EMFDC_PlgBlt()`, the bounding-box computation loop updates `x_min`, `y_min`, `x_max` correctly with `min()`/`max()` against their own running value, but `y_max` is computed with `max( y_min, points[i].y )` instead of `max( y_max, points[i].y )`. This is a copy-paste typo that makes the computed `emr->rclBounds.bottom` wrong whenever `y_max` and `y_min` diverge. **Locations:** dlls/gdi32/emfdc.c:1875 ``` x_min = min( x_min, points[i].x ); y_min = min( y_min, points[i].y ); x_max = max( x_max, points[i].x ); y_max = max( y_min, points[i].y ); ``` **Fix:** ```c // before y_max = max( y_min, points[i].y ); // after y_max = max( y_max, points[i].y ); ``` //////////////////////////////////////////////////// ### CPY_52 `MEDIUM` **Description:** In `ace_flags_to_samba()` the branch for `CONTAINER_INHERIT_ACE` sets `SEC_ACE_FLAG_NO_PROPAGATE_INHERIT` instead of `SEC_ACE_FLAG_CONTAINER_INHERIT`. This is a copy-paste from the next line (`NO_PROPAGATE_INHERIT_ACE`), so `CONTAINER_INHERIT_ACE` is silently dropped and duplicated as `NO_PROPAGATE_INHERIT_ACE` whenever a share's DACL/SACL ACE flags are converted for Samba, corrupting ACL inheritance semantics passed to `NetShareAdd`/`NetShareGetInfo`. **Locations:** dlls/netapi32/unixlib.c:427 ``` if (flags & OBJECT_INHERIT_ACE) ret |= SEC_ACE_FLAG_OBJECT_INHERIT; if (flags & CONTAINER_INHERIT_ACE) ret |= SEC_ACE_FLAG_NO_PROPAGATE_INHERIT; if (flags & NO_PROPAGATE_INHERIT_ACE) ret |= SEC_ACE_FLAG_NO_PROPAGATE_INHERIT; ``` **Fix:** Change the `CONTAINER_INHERIT_ACE` mapping to use the correct destination flag: ```c if (flags & OBJECT_INHERIT_ACE) ret |= SEC_ACE_FLAG_OBJECT_INHERIT; if (flags & CONTAINER_INHERIT_ACE) ret |= SEC_ACE_FLAG_CONTAINER_INHERIT; if (flags & NO_PROPAGATE_INHERIT_ACE) ret |= SEC_ACE_FLAG_NO_PROPAGATE_INHERIT; ``` -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 4123] Picasa: "Open with..." menu item grayed out.

by WineHQ Bugzilla

http://bugs.winehq.org/show_bug.cgi?id=4123 --- Comment #16 from Bruno Jesus <00cpxxx(a)gmail.com> --- Created attachment 81940 --> http://bugs.winehq.org/attachment.cgi?id=81940 Picasa open with menu in Portuguese I known it is weird but you have to wait a few minutes before the Open with menu turns into enabled. Maybe Picasa is doing defunct network stuff and only after that it will scan for other compatible programs in the registry. The picture attached is in Portuguese by hopefully it is clear to show that in Windows XP the default Windows viewer program is there (first) and MS Paint (second) as well. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
