2019-07 Security Bulletin: Juniper Secure Analytics (JSA): Multiple vulnerabilities resolved in JSA 7.3.2 Patch 1

Article ID:   JSA10950

Last Updated: 10 Jul 2019

Version:      1.0

Product Affected:
These issues affect the Juniper Secure Analytics (JSA) Series.

Multiple vulnerabilities have been resolved in the Juniper Secure Analytics
(JSA) 7.3.2 Patch 1 release by fixing the vulnerabilities and updating the
third party software packages included with JSA.

The important security issues resolved include:

     CVE           CVSS                           Summary
               5.3 (
               CVSS:3.0/    Juniper JSA 7.3 discloses sensitive information to
CVE-2018-1729  AV:N/AC:L/   unauthorized users. The information can be used to
               PR:N/UI:N/   mount further attacks on the system.
               A:N )
               7.5 (        python before versions 2.7.15, 3.4.9, 3.5.6rc1,
               CVSS:3.0/    3.6.5rc1 and 3.7.0 is vulnerable to catastrophic
CVE-2018-1060  AV:N/AC:L/   backtracking in pop3lib's apop() method. An
               PR:N/UI:N/   attacker could use this flaw to cause denial of
               S:U/C:N/I:N/ service.
               A:H )
               7.5 (        python before versions 2.7.15, 3.4.9, 3.5.6rc1,
               CVSS:3.0/    3.6.5rc1 and 3.7.0 is vulnerable to catastrophic
CVE-2018-1061  AV:N/AC:L/   backtracking in the difflib.IS_LINE_JUNK method. An
               PR:N/UI:N/   attacker could use this flaw to cause denial of
               S:U/C:N/I:N/ service.
               A:H )
               7.8 (        An AVX-512-optimized implementation of the mempcpy
               CVSS:3.0/    function in the GNU C Library (aka glibc or libc6)
CVE-2018-11237 AV:L/AC:L/   2.27 and earlier may write data beyond the target
               PR:L/UI:N/   buffer, leading to a buffer overflow in
               S:U/C:H/I:H/ __mempcpy_avx512_no_vzeroupper.
               A:H )
                            Constructed ASN.1 types with a recursive definition
               6.5 (        (such as can be found in PKCS7) could eventually
               CVSS:3.0/    exceed the stack given malicious input with
               AV:N/AC:L/   excessive recursion. This could result in a Denial
CVE-2018-0739  PR:N/UI:R/   Of Service attack. There are no such structures
               S:U/C:N/I:N/ used within SSL/TLS that come from untrusted
               A:H )        sources so this is considered safe. Fixed in
                            OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in
                            OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).
                            During key agreement in a TLS handshake using a DH
                            (E) based ciphersuite a malicious server can send a
               7.5 (        very large prime value to the client. This will
               CVSS:3.0/    cause the client to spend an unreasonably long
CVE-2018-0732  AV:N/AC:L/   period of time generating a key for this prime
               PR:N/UI:N/   resulting in a hang until the client has finished.
               S:U/C:N/I:N/ This could be exploited in a Denial Of Service
               A:H )        attack. Fixed in OpenSSL 1.1.0i-dev (Affected
                            1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev
                            (Affected 1.0.2-1.0.2o).


The issues listed above have been resolved in JSA: 7.3.2 Patch 1, and all
subsequent releases.

These issues are being tracked as PR 1445427 which is visible on the Customer
Support website.

There are no known workarounds for this issue, however, limiting access to only
trusted administrators from trusted administrative networks or hosts would
minimize the risk.
