Subject: root-system-xrootd: CVE-2010-3376: insecure library loading
Date: Tue, 28 Sep 2010 21:07:03 +0000
Package: root-system-xrootd
Version: 5.18.00-2.4
Severity: grave
Tags: security

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, an environment variable used by ld.so(8) to look for
libraries on a directory other than the standard paths.

Vulnerable code follows:

/usr/bin/xrdcp line 6:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$rootplugins
/usr/bin/xrdpwdadmin line 6:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$rootplugins
/usr/bin/xrd line 6:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$rootplugins

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-2010-3376. Please make sure
you mention it when forwarding this report to upstream and when fixing
this bug (everywhere: upstream and here at Debian.)
