DESCRIPTION:
Chris Evans has reported some vulnerabilities in Abiword, which
potentially can be exploited by malicious people to compromise a
user's system.

The vulnerabilities are caused due to several boundary errors in the
RTF importer (ie_imp_RTF.cpp). These can be exploited to cause buffer
overflows and may allow arbitrary code execution when importing a
malicious RTF file.

The vulnerabilities affect version 2.2.10 and 2.4.0. Prior versions
may also be affected.

SOLUTION:
Update to version 2.2.11 or 2.4.1.
