[GLSA-200610-06] Mozilla Network Security Service (NSS): RSA signature forgery Vulnerability Scan
Vulnerability Scan Summary
Mozilla Network Security Service (NSS): RSA signature forgery
Detailed Explanation for this Vulnerability Test
The remote host is affected by the vulnerability described in GLSA-200610-06
(Mozilla Network Security Service (NSS): RSA signature forgery)
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.
Impact
Since several Certificate Authorities (CAs) are using an exponent of 3
it might be possible for a possible hacker 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.
Workaround
There is no known workaround at this time.

Solution:
All NSS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/nss-3.11.3"
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.
Threat Level: Medium
