Background ========== Smb4K is a SMB/CIFS (Windows) share browser for KDE. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/smb4k < 0.6.10a >= 0.6.10a Description =========== Kees Cook of the Ubuntu Security Team has identified multiple vulnerabilities in Smb4K. * The writeFile() function of smb4k/core/smb4kfileio.cpp makes insecure usage of temporary files. * The writeFile() function also stores the contents of the sudoers file with incorrect permissions, allowing for the file's contents to be world-readable. * The createLockFile() and removeLockFile() functions improperly handle lock files, possibly allowing for a race condition in file handling. * The smb4k_kill utility distributed with Smb4K allows any user in the sudoers group to kill any process on the system. * Lastly, there is the potential for multiple stack overflows when any Smb4K utility is used with the sudo command. Impact ====== A local attacker could gain unauthorized access to arbitrary files via numerous attack vectors. In some cases to obtain this unauthorized access, an attacker would have to be a member of the sudoers list. Workaround ========== There is no known workaround at this time. Resolution ========== All Smb4K users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/smb4k-0.6.10a" References ========== [ 1 ] CVE-2007-0472 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0472 [ 2 ] CVE-2007-0473 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0473 [ 3 ] CVE-2007-0474 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0474 [ 4 ] CVE-2007-0475 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0475 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-09.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.
