https://bugzilla.suse.com/show_bug.cgi?id=1231159 Bug ID: 1231159 Summary: mc crashes extracting from a compressed tarball Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.6 Hardware: x86-64 OS: Other Status: NEW Severity: Critical Priority: P5 - None Component: Basesystem Assignee: screening-team-bugs@suse.de Reporter: vkrevs@yahoo.com QA Contact: qa-bugs@suse.de Target Milestone: --- Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:130.0) Gecko/20100101 Firefox/130.0 Build Identifier: Download a compressed tarball from github, extract it and recompress it using "tar zcf ...". Then attempt to extract files from the newly created tarball via Midnight Commander and this results in a segfault. Curiously, this does not happen with the original downloaded tarball. Reproduced on my main openSUSE Leap 15.6 dev box and a clean openSUSE Leap 15.6 VirtualBox VM. Reproducible: Always Steps to Reproduce: mkdir ddd && cd ddd wget https://github.com/protocolbuffers/protobuf/releases/download/v21.12/protobu... tar xvf protobuf-cpp-3.21.12.tar.gz tar zcf protobuf-3.21.12.tgz protobuf-3.21.12 l protobuf-3.21.12.tgz protobuf-cpp-3.21.12.tar.gz ; file protobuf-cpp-3.21.12.tar.gz protobuf-3.21.12.tgz -rw-r--r-- 1 user1 users 4942918 Sep 30 19:03 protobuf-3.21.12.tgz -rw-r--r-- 1 user1 users 4842303 Dec 14 2022 protobuf-cpp-3.21.12.tar.gz protobuf-cpp-3.21.12.tar.gz: gzip compressed data, max compression, from Unix protobuf-3.21.12.tgz: gzip compressed data, from Unix mkdir ccc Now start mc and open the "ccc" and "ddd" folders in its panels Position the mc's cursor over the created protobuf-3.21.12.tgz and hit Enter to view the contents of the compressed tarball, then press the down arrow to position the cursor over "protobuf-3.21.12" directory inside the tarball. press F5 and Enter.
