Description Agostino Sarubbo gentoo-dev 2014-01-15 13:39:01 UTC
From ${URL} :


A security issue has been reported in Network Security Services (NSS), which can be exploited by 
malicious people to disclose certain information.

The security issue is caused due an error within the "ssl_Do1stHandshake()" function 
(lib/ssl/sslsecur.c) and can be exploited to potentially return unencrypted and unauthenticated 
data from PR_Recv.

Successful exploitation requires that false start is enabled.

The security issue is reported in versions prior to 3.15.4.

Update to version 3.15.4.

Provided and/or discovered by:
Reported by the vendor.

Original Advisory:

CVE-2013-1740 (
  The ssl_Do1stHandshake function in sslsecur.c in libssl in Mozilla Network
  Security Services (NSS) before 3.15.4, when the TLS False Start feature is
  enabled, allows man-in-the-middle attackers to spoof SSL servers by using an
  arbitrary X.509 certificate during certain handshake traffic.
