Created attachment 1367521 [details] Example bad CRCs with Deflate64 on RHEL7 Description of problem: On RHEL7 unzip doesn't properly extract files compressed with Deflate64 (PKZIP version 2.1). It works fine on RHEL6. I looked through the patches but wasn't able to determine what was different that caused the problem. Version-Release number of selected component (if applicable): unzip-6.0-5.el6.x86_64 - good unzip-6.0-16.el7.x86_64 - bad How reproducible: Use PKZIP to create an archive using Deflate64 compression. Info-Zip 'zip' in RHEL appears to not support Deflate64 for compression. I have attached an example archive. Actual results: RHEL7 unzip -t -v test-file.zip Archive: test-file.zip testing: test-file.1 OK testing: test-file.10 bad CRC 33116a89 (should be b9f107df) testing: test-file.11 bad CRC 681f1464 (should be 7dcd9910) testing: test-file.12 bad CRC 18a00bb3 (should be 19b86783) testing: test-file.13 bad CRC 1a1cdeb0 (should be d05bf729) testing: test-file.14 bad CRC 856da232 (should be 34128307) testing: test-file.15 bad CRC 21cbe446 (should be e18e4b1f) testing: test-file.16 bad CRC 79b0e2e0 (should be 0685f733) testing: test-file.17 bad CRC d0721e93 (should be 10de0c60) testing: test-file.18 bad CRC a9ee39d9 (should be 2adc325a) testing: test-file.19 bad CRC afb34d56 (should be b0592893) testing: test-file.2 bad CRC 32ce03a6 (should be 596fbf57) testing: test-file.20 bad CRC 8de22823 (should be 41bf94e4) testing: test-file.3 bad CRC c23590e1 (should be 3ac7dd34) testing: test-file.4 bad CRC 405624b1 (should be 7313de02) testing: test-file.5 bad CRC 96a950c9 (should be 91e87f56) testing: test-file.6 bad CRC 4fe55800 (should be 2b3113f9) testing: test-file.7 bad CRC fc58c3bc (should be 47865a6e) testing: test-file.8 bad CRC 156bf49e (should be 7d61ca45) testing: test-file.9 bad CRC 724bd722 (should be 252aa321) At least one error was detected in /home/ccheney/Downloads/test-file.zip. Expected results: RHEL6 unzip -t -v ../test-file.zip Archive: test-file.zip testing: test-file.1 OK testing: test-file.10 OK testing: test-file.11 OK testing: test-file.12 OK testing: test-file.13 OK testing: test-file.14 OK testing: test-file.15 OK testing: test-file.16 OK testing: test-file.17 OK testing: test-file.18 OK testing: test-file.19 OK testing: test-file.2 OK testing: test-file.20 OK testing: test-file.3 OK testing: test-file.4 OK testing: test-file.5 OK testing: test-file.6 OK testing: test-file.7 OK testing: test-file.8 OK testing: test-file.9 OK No errors detected in compressed data of ../test-file.zip.
