![A fix is available icon](https://www.mend.io/vulnerability-database//wp-content/themes/whitesource/img/icon2.png)
Date: June 9, 2015
The phar_parse_tarfile function in ext/phar/tar.c in PHP before 5.4.41, 5.5.x before 5.5.25, and 5.6.x before 5.6.9 does not verify that the first character of a filename is different from the \0 character, which allows remote attackers to cause a denial of service (integer underflow and memory corruption) via a crafted entry in a tar archive.
