Bug ID: 44157
Summary: The return value of realpath should be tested or
realpath should be avoided
Product: MediaWiki
Version: 1.21-git
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized

There are several places in the code where realpath() is used without verifying
that it didn't return false despite the two cases where realpath returns false:
realpath() returns FALSE on failure, e.g. if the file does not exist.
The running script must have executable permissions on all
directories in the hierarchy, otherwise realpath() will return FALSE.
The permission bit caused bug #44132.
