Debian LTS Advisory DLA-2708-1 [email protected]
https://www.debian.org/lts/security/ Sylvain Beucler

Package : php7.0
Version : 7.0.33-0+deb9u11
CVE ID : CVE-2019-18218 CVE-2020-7071 CVE-2021-21702 CVE-2021-21704
CVE-2021-21705
Debian Bug : 942830 990575
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.
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.
