|\ | | | | RAR5 reader: reject files that declare invalid header flags
| * RAR5 reader: reject files that declare invalid header flagsGrzegorz Antoniak2020-02-024-2/+39
|/ | | | | | | | | | | | | | | One of the fields in RAR5's base block structure is the size of the header. Some invalid files declare a 0 header size setting, which can confuse the unpacker. Minimum header size for RAR5 base blocks is 7 bytes (4 bytes for CRC, and 3 bytes for the rest), so block size of 0 bytes should be rejected at header parsing stage. The fix adds an error condition if header size of 0 bytes is detected. In this case, the unpacker will not attempt to unpack the file, as the header is corrupted. The commit also adds OSSFuzz #20459 sample to test further regressions in this area.

* Implement ARCHIVE_EXTRACT_SAFE_WRITES on WindowsMartin Matuska2020-01-202-62/+157
| | | | | | | As Windows does not support atomic rename/_wrename we have to unlink the file right before calling _wrename leaving a short unsafe window where a different file with the same name can be created and make the rename operation fail.
* Introduce archive_write_disk(3) flag ARCHIVE_EXTRACT_SAFE_WRITESzoulasc2020-01-209-34/+173
| | | | | | | | | | | | | | | | | | | | | | | | | | This flag changes the way that regular files are extracted: Instead of removing existing files first and re-creating them in order to replace their contents, a temporary file is created and when writing to the temporary file is completed, the file is rename(2)d to the final destination name. This has the effect of presenting a consistent view of the file to the system (either the file with the new contents or the file with the old contents). Removing and overwriting the file has the undesired side effect that the the system can either not see the file at all (from the time it is being removed till the time it is being re-created), or worse it can see partial file contents. This is problematic when extracting system files (for example shared libraries). If the existing file that is going to be overwritten is a hard link, for now we unlink it before calling rename(2). This can be done correctly by creating a hardlink to a tmpnam(3) generated file and then use rename(2), but that is fairly intrusive and requires refactoring. Fixes #1289
