GLSA-200610-06 : Mozilla Network Security Service (NSS): RSA signature forgery
medium Nessus Plugin ID 22892
Synopsis
The remote Gentoo host is missing one or more security-related patches.Description
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 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.
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.
