Mandriva Linux Security Advisory 2014-189 – Antoine Delignat-Lavaud, security researcher at Inria Paris in team Prosecco, reported an issue in Network Security Services libraries affecting all versions. He discovered that NSS is vulnerable to a variant of a signature forgery attack previously published by Daniel Bleichenbacher. This is due to lenient parsing of ASN.1 values involved in a signature and could lead to the forging of RSA certificates. The updated NSPR packages have been upgraded to the latest 4.10.7 version. The updated NSS packages have been upgraded to the latest 3.17.1 version which is not vulnerable to this issue. Additionally the rootcerts package has also been updated to the latest version as of 2014-08-05.
