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

2.  Impact Information


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.

3.  Resolution Information


There is no known workaround at this time.


All Calligra users should upgrade to the latest version:

Code Listing 3.1: Resolution

  # emerge --sync
