Common Vulnerabilities and Exposures assigned an identifier CVE-2014-1569 to the following vulnerability: Name: CVE-2014-1569 URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-1569 Assigned: 20140116 Reference: http://www.intelsecurity.com/resources/wp-berserk-analysis-part-1.pdf Reference: https://www.imperialviolet.org/2014/09/26/pkcs1.html Reference: https://www.reddit.com/r/netsec/comments/2hd1m8/rsa_signature_forgery_in_nss/cksnr02 Reference: https://bugzilla.mozilla.org/show_bug.cgi?id=1064670 Reference: https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/NSS_3.17.3_release_notes The definite_length_decoder function in lib/util/quickder.c in Mozilla Network Security Services (NSS) before 3.16.2.4 and 3.17.x before 3.17.3 does not ensure that the DER encoding of an ASN.1 length is properly formed, which allows remote attackers to conduct data-smuggling attacks by using a long byte sequence for an encoding, as demonstrated by the SEC_QuickDERDecodeItem function's improper handling of an arbitrary-length encoding of 0x00. We believe the CVE-2014-1568 issue is required to trigger this bug, and that issue has already been resolved in Red Hat Enterprise Linux: https://access.redhat.com/security/cve/CVE-2014-1568
Created nss tracking bugs for this issue: Affects: fedora-all [bug 1174493]
As RHEL seems to have rebased to nss 3.18.0, are they still vulnerable to this CVE? Given the text of the advisory from Mozilla, it appears as though it only affects 3.17.x before 3.17.3. Thanks in advance.
Changing needinfo from s-r-t@ to Huzaifa. He should be able to answer that.
I am also interested in the answer to David Sirrine's question. Has Huzaifa weighed in?
This issue was fixed in upstream nss-3.17.3 as described in the release notes at: https://developer.mozilla.org/en-US/docs/Mozilla/Projects/NSS/NSS_3.17.3_release_notes Consequently nss packages shipped with Red Hat Enterprise Linux 5, 6 and 7 were rebased to 3.18.0 via the following advisories. Red Hat Enterprise Linux 5: https://rhn.redhat.com/errata/RHBA-2015-0925.html Red Hat Enterprise Linux 6: https://rhn.redhat.com/errata/RHBA-2015-0926.html Red Hat Enterprise Linux 7: https://rhn.redhat.com/errata/RHBA-2015-0965.html This particular rebase fixed this security flaw.
