Description Vincent Danen 2010-10-19 20:16:11 UTC
Ludwig Nussel discovered that tomboy contained a script that 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.

In Fedora, both /usr/bin/tomboy and /usr/bin/tomboy-panel re-set LD_LIBRARY_PATH insecurely:


A solution is to patch the script to use ':+:' properly:
