NVD Description

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

The phar_get_entry_data function in ext/phar/util.c in PHP before 5.5.30 and 5.6.x before 5.6.14 allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a .phar file with a crafted TAR archive entry in which the Link indicator references a file that does not exist.
