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.

We recommend that you upgrade your php7.0 packages.

For the detailed security status of php7.0 please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
