Gentoo Linux Security Advisory

Title: ChaSen: User-assisted execution of arbitrary code (GLSA 201207-03)
Severity: normal
Exploitable: remote
Date: July 09, 2012
Bug(s): #390769
ID: 201207-03

Synopsis

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


Background

ChaSen is a Japanese morphological analysis system.

Affected Packages

Package: app-text/chasen
Vulnerable: < 2.4.4-r2
Unaffected: >= 2.4.4-r2
Architectures: All supported architectures


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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=app-text/chasen-2.4.4-r2"
