[PATCH v3 0/4] MR8020: libs/ldap: Make GSS-SPNEGO SASL plugin work with LDAP server that uses Kerberos authentication.
by Dmitry Timoshkov (＠dmitry) 19 May '25

19 May '25

-- v3: libs/ldap: Encrypted buffer layout is different for NTLM and Kerberos. libs/ldap: sasl_decode() should treat intput buffer as data + token. libs/ldap: sasl_encode() should construct output buffer as data + token. libs/ldap: When initializing security context ask for mutual authentication. https://gitlab.winehq.org/wine/wine/-/merge_requests/8020

[PATCH v3 0/2] MR8067: Fixes for compiler __try/__except support
by Jacek Caban (＠jacek) 19 May '25

19 May '25

This change allows building with compiler exception support enabled (`-DUSE_COMPILER_EXCEPTIONS`) on non-i386 targets. On i386, `_except_handler3` needs to be available. While we provide it as an import from the msvcrt DLLs, that's not sufficient for modules like kernel32. Making this work would likely require moving `_except_handler3` to `winecrt0`. In practice, this fixes the build with Clang, although the resulting binaries do not appear to be fully correct yet. Further investigation is needed, likely on the LLVM side. -- v3: https://gitlab.winehq.org/wine/wine/-/merge_requests/8067

[PATCH 0/2] MR8045: comctl32: Implement EVENT_OBJECT_VALUECHANGE for trackbars.
by Esme Povirk (＠madewokherd) 19 May '25

19 May '25

Unfortunately, this can't be properly tested because of todo's in the message sequence. The event does show up in response to TPM_SETPOS, at least. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/8045

[PATCH v2 0/1] MR8071: ucrtbase/tests: Avoid reading behind buffer in test_swprintf (ASan).
by Bernhard Übelacker 19 May '25

19 May '25

The test `test_swprintf` creates an un-terminated buffer and calls `WideCharToMultiByte` without explicit srclen on it. This patch wraps the buffer into a struct providing a termination without modifying the test itself. <details> <summary>ASan output:</summary> ``` ================================================================= ==ucrtbase_test.exe==532==ERROR: AddressSanitizer: stack-buffer-overflow on address 0x7ffffe1ffac0 at pc 0x6ffffe845638 bp 0x7ffffe1ff030 sp 0x7ffffe1ff078 READ of size 24 at 0x7ffffe1ffac0 thread T0 #0 0x6ffffe845637 in wcslen C:/llvm-mingw/llvm-mingw/llvm-project/compiler-rt/lib/asan/../sanitizer_common\sanitizer_common_interceptors.inc:7215:3 #1 0x6fffff7d1eff in lstrlenW .../wine/include/winbase.h:2574:5 #2 0x6fffff7d2a33 in WideCharToMultiByte .../wine/dlls/kernelbase/locale.c:7382:30 #3 0x000140016e6c in test_swprintf .../wine/dlls/ucrtbase/tests/printf.c:196:9 #4 0x000140015f3e in func_printf .../wine/dlls/ucrtbase/tests/printf.c:891:5 #5 0x00014002da0e in run_test .../wine/include/wine/test.h:765:5 #6 0x00014002d53a in main .../wine/include/wine/test.h:884:12 #7 0x00014002f005 in mainCRTStartup .../wine/dlls/msvcrt/crt_main.c:58:11 #8 0x6fffffc355be in BaseThreadInitThunk .../wine/dlls/kernel32/thread.c:61:24 #9 0x6fffffdbbcc2 in RtlUserThreadStart (C:\windows\system32\ntdll.dll+0x17004bcc2) Address 0x7ffffe1ffac0 is located in stack of thread T0 at offset 256 in frame #0 0x000140016b6f in test_swprintf .../wine/dlls/ucrtbase/tests/printf.c:176 This frame has 8 object(s): [32, 44) 'str_short' (line 177) [64, 80) 'str_justfit' (line 178) [96, 114) 'str_justfits' (line 179) [160, 182) 'str_muchlonger' (line 180) [224, 226) 'str_empty' (line 181) [240, 256) 'buffer' (line 184) [272, 280) 'narrow' (line 185) <== Memory access at offset 256 partially underflows this variable [304, 320) 'narrow_fmt' (line 185) HINT: this may be a false positive if your program uses some custom stack unwind mechanism, swapcontext or vfork (longjmp, SEH and C++ exceptions *are* supported) SUMMARY: AddressSanitizer: stack-buffer-overflow .../wine/include/winbase.h:2574:5 in lstrlenW Shadow bytes around the buggy address: 0x7ffffe1ff800: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ff880: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ff900: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ff980: 00 00 00 00 00 00 00 00 f1 f1 f1 f1 00 04 f2 f2 0x7ffffe1ffa00: 00 00 f2 f2 00 00 02 f2 f2 f2 f2 f2 00 00 06 f2 =>0x7ffffe1ffa80: f2 f2 f2 f2 02 f2 00 00[f2]f2 00 f2 f2 f2 00 00 0x7ffffe1ffb00: f3 f3 f3 f3 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ffb80: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ffc00: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0x7ffffe1ffc80: 00 00 00 00 00 00 00 00 f1 f1 f1 f1 f8 f8 f8 f8 0x7ffffe1ffd00: f8 f8 f8 f8 f3 f3 f3 f3 00 00 00 00 00 00 00 00 Shadow byte legend (one shadow byte represents 8 application bytes): Addressable: 00 Partially addressable: 01 02 03 04 05 06 07 Heap left redzone: fa Freed heap region: fd Stack left redzone: f1 Stack mid redzone: f2 Stack right redzone: f3 Stack after return: f5 Stack use after scope: f8 Global redzone: f9 Global init order: f6 Poisoned by user: f7 Container overflow: fc Array cookie: ac Intra object redzone: bb ASan internal: fe Left alloca redzone: ca Right alloca redzone: cb ``` </details> -- v2: ucrtbase/tests: Avoid reading behind buffer in test_swprintf (ASan). https://gitlab.winehq.org/wine/wine/-/merge_requests/8071
