Subject: tangerine: CVE-2010-3381: insecure library loading

Date: Tue, 28 Sep 2010 04:22:47 +0000

Package: tangerine
Version: 0.3.2.2-5
Severity: grave
Tags: security
User: team@security.debian.org
Usertags: ldpath

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/tangerine line 7:
export LD_LIBRARY_PATH=${exec_prefix}/lib/tangerine:$LD_LIBRARY_PATH
/usr/bin/tangerine-properties line 8:
export LD_LIBRARY_PATH=${exec_prefix}/lib/tangerine:$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-2010-3381. Please make sure
you mention it when forwarding this report to upstream and when fixing
this bug (everywhere: upstream and here at Debian.)

Thanks for the patch. No need to NMU though: I'll take a run at these
