Microsoft: Windows issue causes file copying, saving failures


Microsoft says some 32-bit applications are impacted by recurring failures when saving and copying files across multiple Windows versions (especially when copying to network shares).

The intermittent issue only affects apps that are large address aware and are also using the CopyFile API on Windows 11 21H2 and 22H2 (after installing KB5023774 or later issued updates) or Windows 10 21H2 and 22H2 (after installing KB5023773 or newer updates).

“Windows devices are more likely to be affected by this issue when using some commercial/enterprise security software which uses extended file attributes,” Microsoft said.

According to Redmond, there have been no reports of File Explorer’s file copying functionality being affected; however, the CopyFile API used within specific applications may be impacted.

Microsoft Office apps like Word and Excel are susceptible to this problem only when utilizing 32-bit versions, with impacted users potentially receiving “Document not saved” error messages.

This known issue is unlikely to be encountered by consumers using Windows devices in personal or non-managed commercial settings.

The findings come from the AhnLab Security Emergency response Center (ASEC), which detailed the advanced persistent threat’s (APT) continued abuse of DLL side-loading techniques to run arbitrary payloads.

“The threat actor places a malicious DLL (msvcr100.dll) in the same folder path as a normal application (Wordconv.exe) via the Windows IIS web server process, w3wp.exe,” ASEC explained. “They then execute the normal application to initiate the execution of the malicious DLL.”
