NVD Description

Note: Versions mentioned in the description apply only to the upstream php-mysql package and not the php-mysql package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
