Description

The phar_parse_zipfile function in zip.c in the PHAR extension in PHP before 5.5.33 and 5.6.x before 5.6.19 allows remote attackers to obtain sensitive information from process memory or cause a denial of service (out-of-bounds read and application crash) by placing a PK\x05\x06 signature at an invalid location.
