Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST."

Buffer overflow in the apache_request_headers function in sapi/cgi/cgi_main.c in PHP 5.4.x before 5.4.3 allows remote attackers to cause a denial of service (application crash) via a long string in the header of an HTTP request.

Thinkphp 5.1.41 and 5.0.24 has a code logic error which causes file upload getshell.

ThinkPHP Framework v5.0.24 was discovered to be configured without the PATHINFO parameter. This allows attackers to access all system environment parameters from index.php. NOTE: this is disputed by a third party because system environment exposure is an intended feature of the debugging mode.

WeiPHP 5.0 does not properly restrict access to pages, related to using POST.

SQL injection vulnerability in the wp_where function in WeiPHP 5.0.

In PHP versions 7.2.x below 7.2.29, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using get_headers() with user-supplied URL, if the URL contains zero (\0) character, the URL will be silently truncated at it. This may cause some software to make incorrect assumptions about the target of the get_headers() and possibly send some information to a wrong server.

regcomp in the BSD implementation of libc is vulnerable to denial of service due to stack exhaustion.

PHP5 before 5.4.4 allows passing invalid utf-8 strings via the xmlTextWriterWriteAttribute, which are then misparsed by libxml2. This results in memory leak into the resulting output.

The plural form formula in ngettext family of calls in php-gettext before 1.0.12 allows remote attackers to execute arbitrary code.
