The Arora and Rekonq web browsers are also vulnerable to the same attack

the Qt team to help enhance their documentation to warn developers to
take care sanitizing their inputs, but it's not actually a Qt flaw. So
we're a bit unsure how to proceed here.
This sounds like a limitation of the Qt API, which can be avoided by
programmers who are aware of the limitation. Kind of like how strcpy()
can be subject to buffer overflows, *if* the programmer isn't careful.
Also happened with confusing return values from certain OpenSSL API
functions a couple years ago. (The PHP_SELF example is similar.) So,
this should probably get separate CVEs for each application/library that
misuses the relevant function(s).
If Qt itself contains misuse of its own functions - which happens
sometimes (CVE-2008-5077 for OpenSSL) - then Qt might need its own CVE,
