In PHP versions 7.4.x below 7.4.30, 8.0.x below 8.0.20, and 8.1.x below 8.1.7, when pdo_mysql extension with mysqlnd driver, if the third party is allowed to supply host to connect to and the password for the connection, password of excessive length can trigger a buffer overflow in PHP, which can lead to a remote code execution vulnerability.
2	CVE-2021-21704	119	DoS Overflow Mem. Corr.	2021-10-04	2021-11-03	4.3	None	Remote	Medium	Not required	None	None	Partial
In PHP versions 7.3.x below 7.3.29, 7.4.x below 7.4.21 and 8.0.x below 8.0.8, when using Firebird PDO driver extension, a malicious database server could cause crashes in various database functions, such as getAttribute(), execute(), fetch() and others by returning invalid response data that is not parsed correctly by the driver. This can result in crashes, denial of service or potentially memory corruption.
3	CVE-2019-11039	125	Overflow	2019-06-19	2020-10-16	6.4	None	Remote	Low	Not required	Partial	None	Partial
Function iconv_mime_decode_headers() in PHP versions 7.1.x below 7.1.30, 7.2.x below 7.2.19 and 7.3.x below 7.3.6 may perform out-of-buffer read due to integer overflow when parsing MIME headers. This may lead to information disclosure or crash.
4	CVE-2019-9675	119	Overflow	2019-03-11	2019-06-03	6.8	None	Remote	Medium	Not required	Partial	Partial	Partial
DISPUTED An issue was discovered in PHP 7.x before 7.1.27 and 7.3.x before 7.3.3. phar_tar_writeheaders_int in ext/phar/tar.c has a buffer overflow via a long link value. NOTE: The vendor indicates that the link value is used only when an archive contains a symlink, which currently cannot happen: "This issue allows theoretical compromise of security, but a practical attack is usually impossible."
5	CVE-2019-9025	119	Overflow	2019-02-22	2021-07-21	7.5	None	Remote	Low	Not required	Partial	Partial	Partial
An issue was discovered in PHP 7.3.x before 7.3.1. An invalid multibyte string supplied as an argument to the mb_split() function in ext/mbstring/php_mbregex.c can cause PHP to execute memcpy() with a negative argument, which could read and write past buffers allocated for the data.
6	CVE-2019-6977	787	Overflow	2019-01-27	2020-08-24	6.8	None	Remote	Medium	Not required	Partial	Partial	Partial

An issue was discovered in Oniguruma 6.2.0, as used in Oniguruma-mod in Ruby through 2.4.1 and mbstring in PHP through 7.1.5. A stack out-of-bounds write in onigenc_unicode_get_case_fold_codes_by_str() occurs during regular expression compilation. Code point 0xFFFFFFFF is not properly handled in unicode_unfold_key(). A malformed regular expression could result in 4 bytes being written off the end of a stack buffer of expand_case_fold_string() during the call to onigenc_unicode_get_case_fold_codes_by_str(), a typical stack buffer overflow.
