Debian 9: DLA-2708-1 Critical: php7.0 DoS and Code Execution Risks

CVE-2019-18218

fileinfo: cdf_read_property_info in cdf.c does not restrict the
number of CDF_VECTOR elements, which allows a heap-based buffer
overflow (4-byte out-of-bounds write).

CVE-2020-7071

When validating URL with functions like filter_var($url,
FILTER_VALIDATE_URL), PHP will accept an URL with invalid password
as valid URL. This may lead to functions that rely on URL being
valid to mis-parse the URL and produce wrong data as components of
the URL.

CVE-2021-21702

When using SOAP extension to connect to a SOAP server, a malicious
SOAP server could return malformed XML data as a response that
would cause PHP to access a null pointer and thus cause a crash.

CVE-2021-21704

Multiple firebird issues.

CVE-2021-21705

SSRF bypass in FILTER_VALIDATE_URL.

For Debian 9 stretch, these problems have been fixed in version
7.0.33-0+deb9u11.
