Background ========== The Mozilla Network Security Service is a library implementing security features like SSL v2/v3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12, S/MIME and X.509 certificates. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 dev-libs/nss < 3.11.5 >= 3.11.5 Description =========== iDefense has reported two potential buffer overflow vulnerabilities found by researcher "regenrecht" in the code implementing the SSLv2 protocol. Impact ====== A remote attacker could send a specially crafted SSL master key to a server using NSS for the SSLv2 protocol, or entice a user to connect to a malicious server with a client-side application using NSS like one of the Mozilla products. This could trigger the vulnerabilities and result in the possible execution of arbitrary code with the rights of the vulnerable application. Workaround ========== Disable the SSLv2 protocol in the applications using NSS. Resolution ========== All NSS users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=dev-libs/nss-3.11.5" References ========== [ 1 ] CVE-2007-0008 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0008 [ 2 ] CVE-2007-0009 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-0009 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200703-22.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. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
