ChaSen: User-assisted execution of arbitrary code

ChaSen: User-assisted execution of arbitrary code A buffer overflow vulnerability in ChaSen could result in the execution of arbitrary code. ChaSen 2012-07-09 2012-07-09 390769 remote 2.4.4-r2 2.4.4-r2

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"
