Unbounded Memory Access Vulnerability in PHP ZIP Signature Verification

CVE-2016-7414 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
