A man-in-the-middle attacker able to force a TLS connection touse the MD5 hash function could use this flaw to conduct collision attacksto impersonate a TLS server or an authenticated TLS client. (CVE-2015-7575)All nss users are advised to upgrade to these updated packages, whichcontain a backported patch to correct this issue.
