Description Huzaifa S. Sidhpurwala 2010-10-08 00:58:24 EDT
Dmitri Gribenko discovered that the soffice script in the Openoffice.org package contained an insecure setting for the LD_LIBRARY_PATH, which could be abused by an attacker to execute arbitrary code.

The vulnerability is due to an insecure change to LD_LIBRARY_PATH, and
environment variable used by ld.so(8) to look for libraries in directories
other than the standard paths.  When there is an empty item in the
colon-separated list of directories in LD_LIBRARY_PATH, ld.so(8) treats it as a
'.' (current working directory).  If the given script is executed from a
directory where a local attacker could write files, there is a chance for
exploitation.

Currently in our soffice script we do...

LD_LIBRARY_PATH=$my_path${LD_LIBRARY_PATH+:$LD_LIBRARY_PATH}

while we should do...

LD_LIBRARY_PATH=$my_path${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}

so if someone currently does
export LD_LIBRARY_PATH=
then our LD_LIBRARY_PATH ends up as
LD_LIBRARY_PATH=/path:
which has an empty entry which effectively means
LD_LIBRARY_PATH=/path:.

Acknowledgements:

Red Hat would like to thank Dmitri Gribenko for reporting this issue.
