CVE-2016-7414

CRITICAL9.8

The ZIP signature-verification feature in PHP before 5

Published Sep 17, 2016

Modified 1 years ago

Details

The ZIP signature-verification feature in PHP before 5.6.26 and 7.x before 7.0.11 does not ensure that the uncompressed_filesize field is large enough, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via a crafted PHAR archive, related to ext/phar/util.c and ext/phar/zip.c.
