CVE-2015-4021

php: memory corruption in phar_parse_tarfile caused by empty entry file name

Published Jun 9, 2015 CVSS 2.0 · 5.0 Medium EPSS 20.5% KEV · Not listed
Description
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.
