CVE-2013-1740

First published: Wed Jan 15 2014(Updated: )

A security issue has been reported in NSS, which can be exploited by a malicious user to disclose certain information. The issue arises due to an error within the "ssl_Do1stHandshake()" function in lib/ssl/sslsecur.c, which can be exploited to potentially return unencrypted and unauthenticated data from PR_Recv. Successful exploitation requires false start to be enabled. The issue is said to be fixed in NSS 3.15.4.
