Re: CVE request: insecure temporary file handling in clang's scan-build utility

Hash: SHA1

Jakub Wilk discovered that clang's scan-build utility insecurely handled
temporary files.

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=744817

The GetHTMLRunDir subroutine ...

3) The function doesn't fail if the directory already exists, even if 
it's owned by another user.

Use CVE-2014-2893.


[ other notes:

1) The directory name is easily predictable

This doesn't seem to be independently exploitable.

2) The directory is created with default permissions (instead of 0700).

Using default permissions is not necessarily wrong, from a CVE
perspective, in all development environments. See the
http://openwall.com/lists/oss-security/2014/03/09/1 post. In any case,
we're not currently making a separate CVE assignment for the
permissions issue. ]
