Debian LTS: Security Advisory for php7.0 (DLA-2708-1)

The remote host is missing an update for the 'php7.0' package(s) announced via the DLA-2708-1 advisory.

Several vulnerabilities were discovered in php5, a server-side, HTML-embedded scripting language. An attacker could cause denial of service (DoS), memory corruption and potentially execution of arbitrary code, and server-side request forgery (SSRF) bypass. 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.
