Two security issues have been identified and fixed in php5, a server-side, HTML-embedded scripting language.

CVE-2020-7062 is about a possible null pointer derefernce, which would likely lead to a crash, during a failed upload with progress tracking. CVE-2020-7063 is about wrong file permissions of files added to tar with Phar::buildFromIterator when extracting them again.
