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 ------------------------------------------------------------------- 1 app-text/unrtf < 0.19.3-r1 >= 0.19.3-r1
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"
