ChaSen is a Japanese morphological analysis system.
An error in chalib.c of ChaSen could cause a buffer overflow.
A remote attacker could entice a user to open a specially crafted text file using ChaSen or an application using the ChaSen libraries, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.
There is no known workaround at this time.
All ChaSen users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-text/chasen-2.4.4-r2"
