Description

'sheepman' fixed a vulnerability in Ruby 1.8: DL::dlopen could open a library with tainted name even if $SAFE > 0.

For Debian 6 'Squeeze', this issue has been fixed in ruby1.8 1.8.7.302-2squeeze5.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
