Created php tracking bugs for this issue: Affects: fedora-all [bug 1223447] php-5.6.9-1.fc22 has been pushed to the Fedora 22 stable repository. If problems still persist, please make note of it in this bug report. php-5.6.9-1.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report. php-5.5.25-1.fc20 has been pushed to the Fedora 20 stable repository. If problems still persist, please make note of it in this bug report. If file name of a file in PHAR archive is empty, it causes out-of-bounds read. Depending on platform, this out of bounds read may be likely to cause crash (e.g. on 64 bit platforms). If the accessed memory is mapped and contains '/', it is overwritten with '\0' and file name length counter is decremented. This may lead to further out of bounds accesses. This issue should only be relevant in use case where Phar archives are opened / inspected, but no code is run from them. Expected use of Phar archives is provide a single file bundle containing PHP application or library, and hence need to be fully trusted as code from archives is executed.
