Package: nordugrid-arc-nox-arex Version: 1.1.0~rc6-2+b1 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, an environment variable used by ld.so(8) to look for libraries on a directory other than the standard paths. Vulnerable code follows: /etc/init.d/a-rex line 281: LD_LIBRARY_PATH=$ARC_LOCATION/lib:$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-2010-3372. Please make sure you mention it when fixing this bug. You should coordinate with the release team in order to fix this bug for Squeeze.
