Severity: grave

Hello,
During a review of the Debian archive, I've found your package to
contain a script that can be abused by an attacker to execute arbitrary
code.
The vulnerability is introduced by an insecure change to
LD_LIBRARY_PATH, and environment variable used by ld.so(8) to look for
libraries on a directory other than the standard paths.
Vulnerable code follows:
/usr/bin/qtcreator line 34:
LD_LIBRARY_PATH="${libdir}/qtcreator:${LD_LIBRARY_PATH}"
When there's an empty item on the colon-separated list of
LD_LIBRARY_PATH, ld.so treats it as '.' (i.e. CWD/$PWD.)
If the given script is executed from a directory where a potential,
local, attacker can write files to, there's a chance to exploit this
bug.
This vulnerability has been assigned the CVE id CVE-2010-3374. Please make sure
you mention it when fixing. Upstream is already aware of this issue.
