Background ========== LinPopUp is a graphical application that acts as a frontend to Samba client messaging functions, allowing a Linux desktop to communicate with a Microsoft Windows computer that runs Winpopup. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-im/linpopup < 2.0.4-r1 >= 2.0.4-r1 Description =========== Stephen Dranger discovered that LinPopUp contains a buffer overflow in string.c, triggered when replying to a remote user message. Impact ====== A remote attacker could craft a malicious message that, when replied using LinPopUp, would exploit the buffer overflow. This would result in the execution of arbitrary code with the privileges of the user running LinPopUp. Workaround ========== There is no known workaround at this time. Resolution ========== All LinPopUp users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-im/linpopup-2.0.4-r1" References ========== [ 1 ] CAN-2004-1282 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2004-1282 [ 2 ] Stephen Dranger Advisory http://tigger.uic.edu/~jlongs2/holes/linpopup.txt Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200501-01.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.
