Description Agostino Sarubbo gentoo-dev 2012-01-13 12:21:16 UTC
From secunia security advisory at $URL:

The weakness is caused due to child processes being able to change the memory type record of the "scoreboard" shared memory segment, which can be exploited to cause an invalid free operation during the shutdown of the parent process.

Fixed in the SVN repository.
