Subject: CVE Request -- perl -- lc(), uc() routines are laundering tainted

Hello Josh, Steve, vendors,

   A security flaw was found in the way Perl performed
laundering of tainted data. A remote attacker could
use this flaw to bypass Perl TAINT mode protection
mechanism (leading to commands execution on dirty
arguments or file system access via contaminated
variables) via specially-crafted input provided
to the web application / CGI script.

Upstream bug report:

Relevant patch:
(contains also information when the issue was introduced)


Could you allocate a CVE id for this?

Thanks && Regards, Jan.
