CVE-2014-3981

Name of the Vulnerable Software and Affected Versions PHP versions 5.5.13 and earlier

Description The issue allows a local user to overwrite arbitrary files by exploiting a symlink attack on the /tmp/phpglibccheck file. This is due to a vulnerability in acinclude.m4, which is used in the configure script in PHP.

Recommendations For PHP versions 5.5.13 and earlier, consider restricting access to the /tmp/phpglibccheck file to prevent exploitation. As a temporary workaround, avoid using the configure script until a patch is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
