Date:	09/30/2005
Bugs:	#107351
ID:	200509-20

Synopsis

AbiWord is vulnerable to a stack-based buffer overflow during RTF import, making it vulnerable to the execution of arbitrary code.

Background

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

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-office/abiword	< 2.2.10	>= 2.2.10	All supported architectures

Description

Chris Evans discovered that the RTF import function in AbiWord is vulnerable to a stack-based buffer overflow.

Impact

An attacker could design a malicious RTF file and entice the user to import it in AbiWord, potentially resulting in the execution of arbitrary code with the rights of the user running AbiWord.

Workaround

There is no known workaround at this time.

Resolution

All AbiWord users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/abiword-2.2.10"
