http://security.gentoo.org/

Severity:	normal
Title:	UnRTF: Buffer overflow
Date:	01/10/2005
Bugs:	#74480
ID:	200501-15

Synopsis

A buffer overflow in UnRTF allows an attacker to execute arbitrary code by way of a specially crafted RTF file.

Background

UnRTF is a utility to convert files in the Rich Text Format into other formats.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-text/unrtf	< 0.19.3-r1	>= 0.19.3-r1	All supported architectures

Description

An unchecked strcat() in unrtf may overflow the bounds of a static buffer.

Impact

Using a specially crafted file, possibly delivered by e-mail or over the web, an attacker may execute arbitrary code with the permissions of the user running UnRTF.

Workaround

There is no known workaround at this time.

Resolution

All unrtf users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-text/unrtf-0.19.3-r1"
