CVE-2020-7069

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when AES-CCM mode is used with openssl_encrypt() function with 12 bytes IV, only first 7 bytes of the IV is actually used. This can lead to both decreased security and incorrect encryption data.

PHP is an HTML-embedded scripting language. PHP attempts to make it easy for developers to write dynamically generated web pages. PHP also offers built-in database integration for several commercial and non-commercial database management systems, so writing a database-enabled webpage with PHP is fairly simple. The most common use of PHP coding is probably as a replacement for CGI scripts. The php package contains the module (often referred to as mod_php) which adds support for the PHP language to Apache HTTP Server.

Security Fix(es):

When using certain mbstring functions to convert multibyte encodings, in PHP versions 7.2.x below 7.2.27, 7.3.x below 7.3.14 and 7.4.x below 7.4.2 it is possible to supply data that will cause function mbfl_filt_conv_big5_wchar to read past the allocated buffer. This may lead to information disclosure or crash.(CVE-2020-7060)

In PHP versions 7.2.x below 7.2.34, 7.3.x below 7.3.23 and 7.4.x below 7.4.11, when PHP is processing incoming HTTP cookie values, the cookie names are url-decoded. This may lead to cookies with prefixes like __Host confused with cookies that decode to such prefix, thus leading to an attacker being able to forge cookie which is supposed to be secure. See also CVE-2020-8184 for more information.(CVE-2020-7070)

PHP is an HTML-embedded scripting language commonly used with the Apache HTTP Server.

The following packages have been upgraded to a later upstream version: php (7.4.19). (BZ#1944110)

Security Fix(es):

• php: Wrong ciphertext/tag in AES-CCM encryption for a 12 bytes IV (CVE-2020-7069)

• php: FILTER_VALIDATE_URL accepts URLs with invalid userinfo (CVE-2020-7071)

• php: Use of freed hash key in the phar_parse_zipfile function (CVE-2020-7068)

• php: URL decoding of cookie names can lead to different interpretation of cookies between browser and server (CVE-2020-7070)

• php: NULL pointer dereference in SoapClient (CVE-2021-21702)

It was discovered that PHP incorrectly handled certain encrypt ciphers. An attacker could possibly use this issue to decrease security or cause incorrect encryption data. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2020-7069)
