Synopsis

AbiWord is vulnerable to an additional set of buffer overflows during RTF import, making it vulnerable to the execution of arbitrary code.

2.  Impact Information

Background

AbiWord is a free and cross-platform word processing program. It allows to import RTF files into AbiWord documents.

Description

Chris Evans discovered a different set of buffer overflows than the one described in GLSA 200509-20 in the RTF import function in AbiWord.

There is no known workaround at this time.

Resolution

All AbiWord users should upgrade to the latest version:

Code Listing 3.1: Resolution
