Package: ust-bin
Version: 0.7-1
Severity: grave
Tags: security
User: t...@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/usttrace line 136:
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:${LIBUST_PATH%libust.so}"
/usr/bin/usttrace line 144:
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:${LIBUST_PATH%libust.so}"
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-2010-3386. Please make sure
you mention it when forwarding this report to upstream and when fixing
this bug (everywhere: upstream and here at Debian.)
