+ <title>Mozilla Network Security Service (NSS): RSA signature forgery</title>

+ NSS fails to properly validate PKCS #1 v1.5 signatures.

+ <p>
+ The Mozilla Network Security Service is a library implementing security
+ features like SSL v.2/v.3, TLS, PKCS #5, PKCS #7, PKCS #11, PKCS #12,
+ S/MIME and X.509 certificates.
+ </p>
+ </background>
+ <description>
+ <p>
+ Daniel Bleichenbacher discovered that it might be possible to forge
+ signatures signed by RSA keys with the exponent of 3. This affects a
+ number of RSA signature implementations, including Mozilla's NSS.
+ </p>
+ </description>
+ <impact type="normal">
+ <p>
+ Since several Certificate Authorities (CAs) are using an exponent of 3
+ it might be possible for an attacker to create a key with a false CA
+ signature. This impacts any software using the NSS library, like the
+ Mozilla products Firefox, Thunderbird and Seamonkey.
+ </p>
+ </impact>
+ <workaround>
+ <p>
+ There is no known workaround at this time.
+ </p>
+ </workaround>
+ <resolution>
+ <p>
+ All NSS users should upgrade to the latest version:
+ </p>
+ <code>
+ # emerge --sync
+ # emerge --ask --oneshot --verbose "&gt;=dev-libs/nss-3.11.3"</code>
+ <p>
+ Note: As usual after updating a library, you should run
+ 'revdep-rebuild' (from the app-portage/gentoolkit package) to ensure
+ that all applications linked to it are properly rebuilt.
