Mozilla Network Security Service (NSS): RSA signature forgery Detailed Explanation for this Vulnerability Assessment 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.
