Background ========== HylaFAX is an enterprise-class system for sending and receiving facsimile messages and for sending alpha-numeric pages. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/hylafax < 4.2.3-r1 >= 4.2.3-r1 Description =========== Patrice Fournier discovered that HylaFAX runs the notify script on untrusted user input. Furthermore, users can log in without a password when HylaFAX is installed with the pam USE-flag disabled. Impact ====== An attacker could exploit the input validation vulnerability to run arbitrary code as the user running HylaFAX, which is usually uucp. The password vulnerability could be exploited to log in without proper user credentials. Workaround ========== There is no known workaround at this time. Resolution ========== All HylaFAX users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/hylafax-4.2.3-r1" References ========== [ 1 ] CVE-2005-3538 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3538 [ 2 ] CVE-2005-3539 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3539 [ 3 ] HylaFAX release announcement http://www.hylafax.org/content/HylaFAX_4.2.4_release Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200601-03.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.
