WinRAR 7.11 Beta 1​

Feb 26, 2025

• If "Add to archive..." Explorer context menu command is applied to multiple archives in the disk root, for example, d:arc1.rar and d:arc2.rar, WinRAR will propose arc1_rar.rar default name for a new archive. Previous version proposed arc1.rar, updating one of selected archives instead of creating a new one.
• Bugs fixed:
• WinRAR 7.10 failed to update solid archives containing a folder record placed before a file record. It issued the checksum error message and aborted processing. As a result of this fix, this version preserves the original position of such folders after updating and doesn't move them to the end of archive as WinRAR 7.10 did;
• when extracting a file from CAB archive over an existing file, existing files were overwritten, but not truncated. So if existing file was larger than extracted, existing file data had been left at the end of the extracted file;
• if SFX module from "Advanced SFX options" dialog was stored in the compression profile, it was applied as is, even if archive format was changed after selecting the profile. It could result in SFX module mismatching the archive format;
• choosing a value in bytes from drop down list associated with archive dialog "Split to volumes, size" field didn't set units to bytes automatically;
• if SFX "TextDone" command was used together with "Silent" and "TempMode" commands, the completion message was sometimes displayed behind other opened windows.

WinRAR 7.13 Beta 1​

Version 7.13 beta 1

1. Another directory traversal vulnerability, differing from that
in WinRAR 7.12, has been fixed.

When extracting a file, previous versions of WinRAR, Windows versions
of RAR, UnRAR, portable UnRAR source code and UnRAR.dll can be tricked
into using a path, defined in a specially crafted archive,
instead of user specified path.

Unix versions of RAR, UnRAR, portable UnRAR source code
and UnRAR library, also as RAR for Android, are not affected.

We are thankful to Anton Cherepanov, Peter Kosinar, and Peter Strycek
from ESET for letting us know about this security issue.

2. Bugs fixed:

a) WinRAR 7.12 "Import settings from file" command failed to restore
settings, saved by WinRAR versions preceding 7.12;

b) WinRAR 7.12 set a larger than specified recovery size for compression
profiles, created by WinRAR 5.21 and older.
