Calligra: User-assisted execution of arbitrary code

Calligra: User-assisted execution of arbitrary code A buffer overflow vulnerability in Calligra could result in the execution of arbitrary code. calligra 2012-09-25 2012-09-25 428890 remote 2.4.3-r1 2.4.3-r1

Calligra is an office suite by KDE.

An error in the read() function in styles.cpp could cause a heap-based buffer overflow.

A remote attacker could entice a user to open a specially crafted ODF file, 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 Calligra users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=app-office/calligra-2.4.3-r1"
