NSS: Signature forgery attack

Antoine Delignat-Lavaud, security researcher at Inria Paris in team Prosecco, reported an issue in Network Security Services NSS 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...

NSS -- RSA Signature Forgery

The Mozilla Project reports: Antoine Delignat-Lavaud 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...

Cryptographic Issues

Overview Affected versions of this package are vulnerable to Cryptographic Issues. MIT Kerberos 5 aka krb5 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a 1 AD-SIGNEDPATH or 2 AD-KDC-ISSUED signature, and possibly gain...

krb5: krb5 may accept authdata checksums with low-entropy derived keys (MITKRB5-SA-2010-007)

MIT Kerberos 5 aka krb5 1.8.x through 1.8.3 does not reject RC4 key-derivation checksums, which might allow remote authenticated users to forge a 1 AD-SIGNEDPATH or 2 AD-KDC-ISSUED signature, and possibly gain privileges, by leveraging the small key space that results from certain one-byte...
