Detail

Synopsis

A buffer overflow vulnerability in ChaSen could result in the execution of arbitrary code.

Background

ChaSen is a Japanese morphological analysis system.

Description

An error in chalib.c of ChaSen could cause a buffer overflow.

Impact

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.

Workaround

There is no known workaround at this time.

Resolution

All ChaSen users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/chasen-2.4.4-r2"
