CVE-2015-4021
Last modified
CVE-2015-4021 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 20.86% chance of exploitation in the next 30 days.
