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" References ========== [ 1 ] Original Announcement http://tigger.uic.edu/~jlongs2/holes/unrtf.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-15.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
