JSON

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.

Notes

Author	Note

leosilva	php5 in precise is 5.3 and does not support the Zend API needed to fix this issue. Since backport this is to intrusive, marking it as ignored for precise/esm.
