Accuvant Labs has reported a vulnerability in Calligra, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to an error within the "read()" function (filters/words/msword-odf/wv2/src/styles.cpp) when parsing ODF styles and can be exploited to cause a heap-based buffer overflow.
Successful exploitation may allow execution of arbitrary code, but requires tricking a user into opening a specially crafted ODF file.
The vulnerability is reported in versions 2.4.3 and prior.
Solution: Fixed in the GIT repository.
